Fuel cells had a lot of hype in the 1990s and investors poured millions into the technology. But when the technology took longer than expected to get to market, many of them lost their money. In the past 20 years, many advances have been made to improve fuel cell technology and this has created renewed optimistim. Current work is focused on improving durability and driving down costs.

Similar to a battery, a fuel cell releases electricity and has an anode, a cathode and a ion-conducting centre called an electrolyte. Unlike a battery, a fuel cell can generate electricity almost indefinitely, if it has fuel and air. In a fuel cell, the chemical energy of the fuel is released via an electrochemical reaction with oxygen from the air to directly produce electricity. Solid Oxide Fuel Cells (SOFC)achieve very high electrical efficiencies of greater than 50%; using the high-grade heat that is also generated, SOFCs can achieve total efficiency to 90% through cogeneration (p.40). By comparison, burning fossil fuels achieves total efficiencies of only 30% to 45%. In other words, for the same amount of fuel, SOFCs double the energy production with virtually no emissions associated with combustion.

Fuel cells are also quiet and vibration free. They have low maintenance, a long operating life and few moving parts which makes them very reliable. They are also scalable, which means many can be connected to operate as a larger system.

There are five main types of fuel cells. Canada is focused primarily on two. One of these is Proton Exchange Membrane Fuel Cells (PEMFC) that run on hydrogen or alcohol and are well-suited for mobile applications such as cars and laptops. Alberta’s Gen-X Energy (profiled p.38) is pioneering small-sized PEMFCs as well as methanol-powered fuel cells, which is also a focus for Evergreen Energy (profiled p.37).

Canada also has a very strong research program in Solid Oxide Fuel Cells (SOFC), especially in Alberta. SOFCs are ideal for distributed power generation in homes, buildings and industry. SOFCs run on natural gas, diesel or hydrogen. In Alberta, Versa Power Systems (profiled p.38) and DDI Energy (profiled p.37) are SOFC leaders.

With its high profile clients such as Google and eBay, SOFC producer Bloom Energy of Silicon Valley has already become a media darling.

 DDI Energy  
Leader in off-grid power generation systems using Solid Oxide Fuel Cells

A village in Africa will soon be using DDI Energy’s remote power generation system to power their hospitals, schools and orphanages and provide them with up to 100 litres of fresh water a day. DDI Energy specializes in integrating Solid Oxide Fuel Cells (SOFC) with hardware components and control software to create low-maintenance power generation systems for remote locations. DDI Energy makes several scalable systems from 3 to 40 kW that can be powered by natural gas, propane or methane, and can achieve 45% electrical efficiency with very low emissions and operating costs compared to other power sources.

Evergreen Energy
New solar + fuel cell powered generator adds reliability, saves money and reduces environmental impact

A natural gas or oil well site needs a small amount of electricity to keep the well operational and to run monitoring equipment. Being in remote locations, these sites need an off-grid power source. While there are many different kinds of power sources available, many have drawbacks such as fuel inefficiently, the high cost of fuel and refueling, unreliability in harsh weather conditions and high greenhouse gas emissions. Evergreen has developed a new, robust, eco-friendly off-grid power generator (pictured) that runs on solar power when the sun shines. On cloudy days, the generator uses a fuel cell that consumes a small amount of methanol, resulting in very low greenhouse gas emissions.

Gen-X Power
Leader in off-grid power generation systems using Solid Oxide Fuel Cells

World’s first compact user friendly fuel cells could be the next breakthrough At the same size as a D size DC battery, Gen-X Power’s light-weight and transportable fuel cells could be the world’s next plug-and-play power source. Like the DC batteries we use today, Gen-X’s fuel cells have a cylindrical design, which gives it many advantages: they are compact, have improved longevity and are available in modular units with different voltages. This unique design was chosen to keep maintenance low and improve safety. Gen-X’s fuel cell design also uses a minimum amount of expensive noble metals as catalysts, meeting another key requirement of the Holy Grail of fuel cells: affordability. Gen-X’s fuel cell uses a novel capillary membrane created by Whitefox Technologies (p.17) that works with both acidic or alkaline fuels. The company’s manufacturing process is easily scaled up or down to a wide variety of fuel cell sizes and geometries.

Versa Power Systems
North American leader in advanced solid oxide fuel cell (SOFC) stacks and modules

Versa Power Systems develops and builds SOFCs ranging from 5 to 50kW which commercial buildings use to generate their own environmentally-friendly and energy efficient electricity from natural gas. Versa’s SOFCs are engineered to use waste heat and can achieve energy conversion efficiencies up to 85% through cogeneration. Through the US Defense Advanced Research Projects Agency’s Vulture program, Versa is also working with Boeing to develop an unmanned aircraft that can remain in the air at 60,000 to 90,000 feet for at least 5 years and continuously deliver surveillance data to the earth. The aircraft’s energy will be delivered by combining solar power with Versa’s SOFC technology.

SOFCs that run on fuel with impurities
Dr. Hill is exploring how SOFCs can be directly fuelled by hydrocarbons and hydrogen containing impurities. These fuel sources are often found as byproduct energy streams in the oil and gas industry, and energy efficiency would increase if the fuels did not need processing before being used. One challenge in creating robust SOFCs is the effect on the fuel cell components from the high temperatures in which they operate. Another challenge is preventing carbon contained in the fuel from depositing in the fuel cell, which causes the fuel cell to fail.

Ultra low platinum quality catalysts
The best electrodes for fuel cells contain platinum, which is a very expensive element. Dr. Bergens’ nanoparticle engineering research successfully makes equivalent quality electrodes using only a tiny fraction of platinum.

Hydrogen fuel cells without water
Hydrogen fuel cells typically use water to carry a charge in the electrolyte. Drs. Shimizu and Thangadurai have found significant efficiencies and cost savings by using a non-water based electrolyte, a unique porous nano-crystalline material, and operating the fuel cell above 100oC. They are working on commercializing this technology with Canada’s world leader in hydrogen fuel cells, Ballard Power Systems, and are looking for more partners.

Cheaper and more durable fuel cells
Dr. Birss’ team is developing new solid oxide fuel cell (SOFC) anode materials that are highly active, yet stable in sulphur-containing fuels found in Canada. This work, in collaboration with other teams in Canada, who are developing entirely new SOFC designs, will ultimately lower the cost of SOFCs. The team is also replacing expensive noble metals used in Proton Exchange Membrane (PEM) fuel cells and direct alcohol fuel cells with cheaper catalysts that will lower overall cost of this technology. One component of the work is focused on developing novel nanostructured carbon support materials which keep the catalytic nanoparticles firmly attached, preventing carbon degradation and significantly increasing fuel cell lifetime.
