  • Cell for water electrolysis/fuel cell power generation and cell stack body having a plurality of same cells stacked
    Patent number: 11699801
    Abstract: A cell for water electrolysis/fuel cell power generation which includes a 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 or supply an oxygen-containing 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. Each of the oxygen-side electrode layer and the hydrogen-side electrode layer is an electrode layer having water repellency.
    Type: Grant
