Abstract
A porous gas diffusion electrode for polymer electrolyte membrane fuel cells. The electrode contains an electrocatalyst, a polymer electrolyte and nanosized pores. The pores are formed using nanosized pore-formers. The pore-former is applied to a substrate along with a polymer electrolyte and an electrocatalyst and the resulting structure is treated to remove the pore-former.
