Investigation of sulfur dioxide (SO_2) on contamination of the PEFC electrodes and resultant cell performance degradation has been performed by an accelerated degradation test of a single cell and electrochemical diagnostics on model electrodes. It was revealed that two-stage degradation on cell performance by SO2 supply and was presumably caused, depending on the electrode potential. A possible electrochemical reaction to induce this degradation was proposed as sulfur formation process on the catalyst.
