In the present invention, an electrolytic cell (100) has an electrolytic membrane (110), a reduction electrode (120), and an oxygen-generating electrode (130). The electrolytic membrane (110) is formed from a material (ionomer) having proton conductivity. The reducing catalyst used in the reduction electrode (120) comprises a composition containing a first catalytic metal (noble metal) containing Pt and/or Pd, and a second catalytic metal that is one or more elements selected from Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, Ru, Sn, W, Re, Pb, and Bi. The oxygen-generating electrode (130) contains a noble metal oxide catalyst such as RuO |
