PURPOSE: To obtain a solid macromolecular electrolyte electrochemical cell, stably operable at high voltage even in a high electric current density area, by smoothing material transport. CONSTITUTION: In this solid macromolecular electrolyte electrochemical cell, the following are laminated in order, a cathode current collector 2, a cathode catalyst layer 3, a solid macromolecular electrolyte film 4, an anode catalyst layer 5, and an anode current collector 6, Water, produced through a hole, can be made dischargeable in a liquid condition, and an oxidation gas too can be properly supplied, by making the cathode current collector 1 a water- repellently treated conductive nonwoven fabric, and have necessary holes 1 opened at least in a surface contacting the gas. |
