Degradation Resistant Cathodes in Polymer Electrolyte Membrane Fuel Cells

Fuel cells are the most environmentally friendly alternative to internal combustion engine technology in vehicles. They also have applications in stationary and portable power markets because they are energy efficient, clean and fuel flexible. For a Polymer electrolyte membrane fuel cell (PEMFC) to be used commercially in stationary or transportation applications, cost and durability are the major challenges. For transportation applications, fuel cell technologies face more stringent cost and durability requirements: a fuel cell system needs to cost less than $50/kW with a 5,000 hour lifespan (150,000 miles equivalent) and have an ability to function over the full range of vehicle operating conditions (-40° to +90° C).
