摘要： A photoelectrochemical cell (1) is a photoelectrochemical cell for decomposing water by irradiation with light so as to produce hydrogen. This photoelectrochemical cell (1) includes: a conductive substrate; a first electrode (optical semiconductor electrode (3)) including an optical semiconductor and disposed on a first main surface of the conductive substrate; a second electrode (counter electrode (4)) disposed in a region on the first main surface of the conductive substrate where the first electrode is not disposed; an electrolyte containing water and disposed in contact with a surface of the first electrode and a surface of the second electrode; a rib (5) formed to separate a space above the surface of the second electrode from a space above the surface of the first electrode and to extend along a flow direction of a gas produced on the surface of the second electrode, the rib being formed of a material that allows ions to pass therethrough and prevents a gas from passing therethrough; and a container (2) containing the conductive substrate, the first electrode, the second electrode, the electrolyte, and the rib.

摘要： Even if reaction gas flows into a substantially rectangular anode-side and cathode-side gaps formed between an annular main body portion and a membrane electrode assembly in an anode side and a cathode side of a fuel cell, the reaction gas is prevented from flowing out from an outlet without passing through an electrode to cause degradation of power generation efficiency. At least one of anode-side gasket and cathode-side gasket in the fuel cell is provided with an extra sealing portion connected to an annular main body portion in such a manner that, among two pairs of gap portions opposing to each other in the anode-side gap and the cathode-side gap, the extra sealing portion intersects with one pair of gap portions having a larger pressure gradient of fuel gas and oxidant gas in a direction from an upstream side to a downstream side of a fuel gas flow channel and an oxidant gas flow channel.

摘要： A preservation assembly of a polymer electrolyte fuel cell stack is provided. The assembly includes an uninstalled polymer electrolyte fuel cell stack and sealing units. The uninstalled polymer electrolyte fuel cell stack is provided with an oxidizing agent passage having an inlet and an outlet and extending through a cathode and a reducing agent passage having an inlet and an outlet and extending through an anode. The sealing units include sealing plugs or containers and are configured to seal the inlet and the outlet of the oxidizing agent passage within which an oxygen concentration has been decreased and to seal the inlet and the outlet of the reducing agent passage within which the oxygen concentration has been decreased. The uninstalled polymer electrolyte fuel cell stack is in a state before an assembled polymer electrolyte fuel cell stack is incorporated into a fuel cell system.
