Abstract: A hydrogen supply system includes: an electrochemical hydrogen pump including an electrolyte membrane, an anode and a cathode provided to a first and second main surfaces of the electrolyte membrane, respectively, an anode flow path and cathode flow path through which hydrogen flows, and a voltage applicator applying a voltage between the anode and cathode, pressurizing and sending hydrogen supplied to the anode via the anode flow path to the cathode by applying a voltage by the voltage applicator, and supplying the pressurized hydrogen in the cathode flow path to a hydrogen reservoir; a pressure adjuster adjusting a cathode flow path pressure; and a controller controlling the pressure adjuster and making the cathode flow path pressure higher than an anode flow path pressure before starting a hydrogen pressurization action for pressurizing and supplying hydrogen supplied to the anode flow path to the cathode flow path.

Abstract: A hydrogen generation system including: a reformer generating hydrogen-containing gas using a raw material and reforming water; a combustor combusting hydrogen-containing gas and air and generating exhaust gas; a first channel passing cooling water; a condenser generating condensed water by heat exchange between exhaust gas and cooling water; a tank storing condensed water as cooling water; a pump supplying cooling water from the tank to the condenser; a second channel branching at a branch between the pump and condenser in the first channel, and passing some cooling water to the reformer as reforming water; a heater provided downstream of the branch, and heating the first channel; a temperature detector detecting the temperature of the first channel; and a controller, in an activation operation mode, determining whether the second channel is filled with reforming water, based on the temperature detected by the temperature detector after the heater has operated.
