The cost and durability of polymer electrolyte membrane fuel cell (PEMFC) systems have limited their deployment. The relative cost of the balance of plant (BOP) has risen in importance with decreasing fuel cell stack cost. Lowering costs of PEMFC system components require the understanding of potential contaminants from these materials. System contaminants have received very limited attention publicly. We here present ex-situ leaching tests with materials that could be considered as gasket materials to quickly screen BOP component materials. Aliquots of the leachant solutions were collected periodically and analyzed (pH, conductivity, etc.) to identify and quantify contaminants. The influence of the leachant on the electrochemical performance of Pt was also investigated.
