CPC H01M 8/186 (2013.01) [C25B 1/04 (2013.01); C25B 9/73 (2021.01); H01M 8/04201 (2013.01); H01M 8/0656 (2013.01); Y02E 60/36 (2013.01)] | 13 Claims |
1. A water electrolysis cell and/or a fuel power cell and/or a reversible cell, comprising:
a cell stack part in which an oxygen-side electrode layer, an electrolyte layer, a hydrogen-side electrode layer, a first gas separator configured for an oxygen-containing gas separated from a liquid water to pass through therein between the oxygen-side electrode layer and the electrolyte layer, and a second gas separator configured for a hydrogen-containing gas separated from the liquid water to pass through therein between the electrolyte layer and the hydrogen-side electrode layer are stacked, and a catalyst layer is provided between the oxygen-side electrode layer and the electrolyte layer and/or between the electrolyte layer and the hydrogen-side electrode layer;
a water flow path configured to supply or discharge water in a first direction substantially perpendicular to a stacking direction of the cell;
an oxygen-containing gas flow path configured to discharge the oxygen-containing gas separated from a liquid water or supply oxygen gas in a second direction substantially perpendicular to the stacking direction of the cell; and
a hydrogen-containing gas flow path configured to discharge or supply the hydrogen-containing gas in a third direction substantially perpendicular to the stacking direction of the cell,
wherein each of the oxygen-side electrode layer and the hydrogen-side electrode layer is an electrode layer having water repellency, and
the water flow path, the oxygen-containing gas flow path, and the hydrogen-containing gas flow path are completely independent and separated from each other.
