Abstract: A hydrogen system includes a compressor that includes an electrolyte membrane, an anode on a first primary surface of the electrolyte membrane, a cathode on a second primary surface of the electrolyte membrane, and a voltage applicator that applies a voltage between the anode and the cathode, the compressor producing compressed hydrogen by causing the voltage applicator to apply a voltage between the anode and the cathode to move hydrogen in hydrogen-containing-gas containing steam supplied to the anode to the cathode via the electrolyte membrane; a supply path through which the hydrogen-containing-gas containing steam to be supplied to the anode flows; a cooling mechanism disposed in the supply path; and a heat exchanger disposed in the supply path, the heat exchanger exchanging heat between the hydrogen-containing-gas flowing through the supply path upstream of the cooling mechanism and the hydrogen-containing-gas flowing through the supply path downstream of the cooling mechanism.

Abstract: A hydrogen system includes: a compressor in which protons extracted from an anode fluid supplied to an anode move to a cathode through an electrolyte membrane and compressed hydrogen is generated; and a first eliminator including: a water-permeable membrane; a cathode gas flow path through which a cathode gas discharged from the cathode of the compressor flows, the cathode gas flow path being provided on one main surface of the water-permeable membrane; and an accommodation portion provided on the other main surface of the water-permeable membrane and filled with a liquid at a pressure lower than that of the cathode gas. The first eliminator removes moisture contained in the cathode gas.

Abstract: A hydrogen supply system includes: a controller; and an electrochemical hydrogen pump including: an electrolyte membrane; a pair of electrodes provided on two surfaces of the electrolyte membrane; and a current adjuster adjusting a current flowing between the electrodes, the electrochemical hydrogen pump performs a hydrogen supply operation supplying pressure-boosted hydrogen to a hydrogen demander by allowing a current to flow between the electrodes by the current adjuster; and when a cumulative hydrogen supply amount which is supplied to the hydrogen demander from start to completion of the hydrogen supply operation to the hydrogen demander from the electrochemical hydrogen pump is smaller than a cumulative hydrogen supply amount in another hydrogen supply operation, the controller controls the current adjuster so that the current flowing between the electrodes is decreased to be smaller than that in the another hydrogen supply operation.

Abstract: An apparatus includes: an electrolyte membrane; a cathode catalyst layer provided to one main surface of the electrolyte membrane; an anode catalyst layer provided to the other main surface of the electrolyte membrane; a cathode gas diffusion layer provided on a main surface of the cathode catalyst layer not facing the electrolyte membrane; a separator including a recess through which cathode gas flows; an anode gas diffusion layer provided on a main surface of the anode catalyst layer not facing the electrolyte membrane; a voltage applicator applying a voltage between the cathode catalyst layer and the anode catalyst layer; and a fastener fastening a laminated body. The cathode gas diffusion layer is accommodated in the recess, projects from the recess in a thickness direction before fastening of the laminated body, and includes an elastic member between side surfaces of the cathode gas diffusion layer and of the recess.
