Preparation of Advanced CCMs for AMFCs by Amination and Cross-linking of the Precursor Form of the Ionomer

摘要

In an AMFC, in the formation of a CCM, the anode catalyst layer is selectively cross-linked while the cathode catalyst layer is not cross-linked. This has been found to provide structural stabilization of the CCM without loss of initial power value for a CCM without cross-linking.

1. An alkaline membrane fuel cell comprising:
an anode electrode; a membrane electrolyte configured to conduct hydroxyl (OH—) anion, the membrane having an interface in physical contact with the anode electrode on the first surface of the membrane; a cathode electrode in physical contact with second opposite surface of the membrane; the anode electrode and the cathode electrode each having a catalyst layer; wherein an ionomer component of the catalyst layer on the anode electrode is cross-linked to achieve structural stabilization without loss of cell power
