Development of proton exchange membrane fuel cell

With a study on patents of fuel cell issued recent years, some key questions about proton exchange membrane fuel cell(PEMFC)were studied such as polymeric electrolyte membrane, catalyst, electrode and electrode & membrane assembly and design of fluid plate. The development and state of preparing polymer electrolyte membrane, high active catalyst, electrode and electrode & membrane assembly, and designing fluid plate for fuel cells were also studied. It was concluded that it was the base for improving the performance of fuel cell to raise electrode exchange rate and decrease fuel cell internal resistance. Proper design of fluid plate ensured the entire performance. All factors mentioned above were interacted.
