摘要:
An electrode for a fuel cell, a membrane electrode assembly including the electrode, and a fuel cell including the membrane electrode assembly. Due to the inclusion of a barrier layer between a diffusion layer and a catalyst layer, the electrode prevents leakage of phosphoric acid moving from the catalyst layer to the diffusion layer and prolongs the lifetime of the membrane electrode assembly.
摘要:
A catalyst coated membrane (CCM) for a fuel cell, including an electrolyte membrane and a catalyst layer formed on at least one surface of the electrolyte membrane, a membrane and electrode assembly (MEA) for a fuel cell, including the CCM, a method of preparing the MEA, and a fuel cell including the MEA. The CCM is formed directly on the electrolyte membrane.
