Prognosis for Fuel Cells

Almost 170 years after their invention, fuel cells are approaching commercial reality. As we have seen, the space programme that started in the early 1960s 

Specifications for hydrogen purity less stringent than for PEMFCs Uses Pt-based electrocatalyst Corrosion and sintering of positive electrode are problems Most commercially advanced technology 

Fuelled by hydrogen, natural gas, petroleum, propane, landfill gas, biogas, diesel, etc. 

No need for external reformer Uses less expensive (not Pt-based) electrocatalyst Slow start-up 

Slow response to changes in load Corrosion and durability problems Requires carbon dioxide management system
