An efficient Ag-ionomer interface for hydroxide exchange membrane fuel cells
An efficient Ag-phosphonium ionomer interface is discovered in HEMFCs, helping enhance oxygen reduction and improve mass transports simultaneously. As a result, a completely-precious-metal-free HEMFC has been fabricated, which shows a cost-normalized power much higher than that of a Pt-based PEMFC benchmark (117 vs. 7.7 W US$(-1)).
