Abstract
This disclosure relates to electrolyzer composite membranes, and in particular, to a composite membrane having at least two reinforcing layers comprising a microporous polymer structure and a surprisingly high resistance to piercing. The electrolyzer composite membranes have a recombination catalyst configured to be disposed closer to an anode than to a cathode in a membrane-electrode assembly (MEA). The disclosure also relates to membrane-electrode assemblies and electrolyzers comprising the membranes, and to method of manufacture of the membranes.
