Experimental and theoretical investigations of transport processes in polymer electrolyte fuel cells

Canada’s current fossil fuelled transportation sector consumes nearly 30% of our primary energy. Polymer electrolyte fuel cells (PEFCs) and batteries present viable alternatives to replace the current transportation energy system. Hydrogen, produced by water splitting in a polymer electrolyte electrolyzer (PEE) using electricity from renewable energy sources, could be used in PEFCs to power a vehicle. PEFCs produce only water vapor thereby eliminating pollution and greenhouse gas emissions. PEFC vehicles have demonstrated all the attributes that customers expect such as quick start-up and refuelling, long range, and durability. Prerequisites for an increase in market penetration of PEE, and PEFC vehicles, are production cost reductions as well as performance and durability improvements.
