Abstract

Significant improvement in the durability of polymer electrolyte fuel cell (PEFC) electrocatalysts is essential for heavy-duty applications. Carbon-based supports suffer from carbon corrosion during start-stop potential cycles, leading to Pt detachment. Load cycles can also cause degradation mainly associated with Pt dissolution/re-deposition. Here, nanocomposite electrocatalysts with Pt and SnO2 decorated on mesoporous carbon (MC) are prepared for improvement of start-stop and load-cycle durability. These nanocomposite electrocatalysts are found to be deposited within the mesopores of the MC support. It is demonstrated by half-cell tests that such electrocatalysts exhibit a high durability for potential changes simulating start-stop and load-cycles.
