摘要:
The membrane electrode assembly 1 has an anode 10, a cathode 20, and an electrolyte membrane 30 disposed between the anode and cathode; the anode and cathode are gas diffusion electrodes; the electrolyte membrane contains a solid electrolyte in which a plurality of pores with mean pore diameters of 1 to 30 nm are formed; and the solid electrolyte has a backbone comprising organic groups having one or more metal atoms, oxygen atoms bonded to the metal atoms, and carbon atoms bonded to the metal atoms or oxygen atoms, and also has functional groups with ion-exchange capabilities that are bonded to the organic groups in the pores.
摘要:
Disclosed is a membrane electrode assembly obtained by bonding electrodes to both surfaces of a solid polymer electrolyte membrane suitably for use in a solid polymer fuel cell. In order to maintain not only the solid polymer electrolyte but also the electrode in appropriate wet states, the catalyst layer of the assembly contains a metalloxane polymer in the intra-catalyst-layer electrolyte including an electrode catalyst preferably in an amount of 0.5 to 50 wt % of the total weight of the intra-catalyst-layer electrolyte and the metalloxane polymer contained therein exclusive of the electrode catalyst.
