<p>An electrolysis cell 100 has an electrolyte membrane 110, a reduction electrode 120, and an oxygen evolving electrode 130. The electrolyte membrane 110 is formed of a material having protonic conductivity (ionomer). A reduction catalyst used for the reduction electrode 120 is composed of a composition containing a first catalyst metal (noble metal) that contains at least one of Pt and Pd and containing one or more kinds of second catalyst metals selected from among Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, Ru, Sn, W, Re, Pb, and Bi. The oxygen evolving electrode 130 contains catalysts of noble metal oxides such as RuO 2 , IrO 2 , and the like.</p> |
