Membrane electrode array, used in fuel cell, preferably high temperature fuel cell, has polyimide layer on both surfaces of polymer electrolyte membrane in contact with electrochemically active electrodes

摘要

In a membrane electrode array with 2 electrochemically active electrodes separated by a polymer electrolyte membrane (PEM), a polyimide (PI) layer is provided on both surfaces of the PEM in contact with the electrodes. An Independent claim is also included for fuel cells with at least one of these membrane electrode arrays.
