High‐temperature operation of PEMFC using pore‐filling PTFE/Nafion composite membrane treated with electric field

Summary A pore‐filling polytetrafluoroethylene (PTFE)/Nafion composite membrane was developed for the high‐temperature operation of proton‐exchange membrane fuel cell (PEMFC). Porous PTFE substrate was filled with Nafion solution and cast under an electric field to align ion channel in the through‐p...
