文摘

A simple MPL-free GDE is developed for HT-PEMFC application. A micropore/macropore composited CL structure is formed by eliminating MPL. The MPL-free GDE allows easy transports of electrons and gases. Good CL/membrane interfacial contact is still maintained with the MPL-free GDE. The MPL-free GDE exhibits a high performance and durability for HT-PEMFC operation.
