Abstract
Use of a selectively conducting anode component in solid polymer electrolyte fuel cells can reduce the degradation associated with repeated startup and shutdown, but can also adversely affect a cell's tolerance to voltage reversal along with its performance. It was shown that these adverse affects can be mitigated against in certain ways. However, improved results can be obtained by employing a selectively conducting component which comprises a mixed layer of a selectively conducting material and carbon. The mixed layer contacts the side of the anode opposite the solid polymer electrolyte.
