Abstract:
1. A gas decomposition apparatus comprising: a catalytic electrode that contains a catalyst and is porous; a counter electrode that forms a pair with the catalytic electrode; and an electrolyte that is sandwiched between the catalytic electrode and the counter electrode and has ion conductivity, wherein the catalyst is held by the catalytic electrode in a form of being carried by a carrier containing a conductive material or the catalyst is directly carried by the catalytic electrode containing a conductive material as one of constituent materials of the catalytic electrode, the conductive material in the catalytic electrode, the conductive material being in contact with the catalyst, does not include a noncovalent carbon material, the electrolyte mainly includes a uniaxially or biaxially stretched porous polytetrafluoroethylene (PTFE) membrane and a perfluorocarbon ion exchange polymer that fills gaps of the porous PTFE membrane and extends from the catalytic electrode to the counter electrode, and a surface of a fiber of the porous PTFE membrane is covered with a hydrophilic resin film.
