    Abstract: An electrochemical hydrogen pump includes at least one hydrogen pump unit including an electrolyte membrane, an anode on one main surface of the electrolyte membrane, a cathode on the other main surface of the electrolyte membrane, an anode separator on the anode, and a cathode separator on the cathode, the at least one hydrogen pump unit transferring, to the cathode, hydrogen supplied to the anode and pressurizing the hydrogen, a first fixing member for preventing movement of the cathode separator in a direction in which the cathode separator is stacked, a first end plate on the anode separator at one end in the stacking direction, a second end plate on the cathode separator at the other end in the stacking direction, and a first gas flow channel through which hydrogen in the cathode is supplied to a first space between the second end plate and the cathode separator.

    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.
