Electrochemical cell, oxygen reduction device using the cell and refrigerator using the oxygen reduction device

Abstract

According to one embodiment, an electrochemical cell includes an anode, a cathode and an electrolytic membrane interposed therebetween. At least one of the anode and the cathode is formed of an integral solid conductive plate and includes a first surface in contact with the electrolytic membrane and a second surface apart from the first surface in a thickness direction. The at least one of the anode and the cathode includes a plurality of first pores opened in the first surface and a plurality of second pores opened in the second surface, the second pores communicating with a part of the first pores. The first pores are smaller than the second pores, and the concentration of pores in the first surface is higher than that in the second surface.

Dependencies are inferred from the claim text.
