Abstract:

In the process of making electrodes in polymer electrolyte membrane fuel cells(PEMFC), the conventionally used PTFE is replaced by Nafion solution as the binder, whose content in the catalyst layer is optimised. The effects of gas pressure and electrolyte membrane on the performance of oxygen electrode are also studied. It is found that: (1) the performance is improved using Nafion as the binder and the electrode with 2mg?cm-2 Nafion in the catalyst shows the best performance; (2) higher gas pressure improves the preformance of the cell: (3) the performance of the cell with Nafion 115 membrane is better than that with Nafion 117 membrane.
