To provide a hydrogen production apparatus and a hydrogen production method by which hydrogen as a chemical energy with easy storing property can be efficiently and stably produced by using thermal energy, which easily diffuses, so as to effectively use energy.
The hydrogen production method includes steps of: carrying out thermoelectric power generation by installing a thermoelectric power generator (thermoelectric conversion module 11) having a thermoelectric element having a high durable temperature, in a place such as a blast furnace where repeated thermal cycles are relatively few and waste heat at a high temperature is stably obtained through the year; also using the waste heat to convert water from a water supply tank 21 into high temperature steam at about 1,000°C or medium temperature steam at about 600°C by a steam generator (a steam heater 12 and a heat exchanger 14); then electrolyzing the steam to produce hydrogen and oxygen by an electrochemical device (electrolytic device 13) using the generated power; and storing the produced hydrogen and oxygen in a hydrogen tank 23 and an oxygen tank 24, respectively.
