Further, the cooling water stop valve 34 is closed and the heating water stop valve 33 is opened. Therefore, the container 25 is heated by the heat exchanger 29 with the heated water 30 to heat the alloy (metal storage alloy). By heating, the hydrogen gas that has been stored in advance is separated due to the characteristics of the hydrogen storage alloy 29, and is sent to the fuel cell 26 through the three-way switching valve 24. The fuel cell 26 has an air pipe 27 separately from this hydrogen gas.
Generates electricity by reacting with the air taken in more. This generated electric inverter 28 converts DC to AC,
Power is supplied to the main power supply 21. Therefore, the inboard emergency power generator having the above-described structure has the following effects as compared with the conventional emergency power generator using the diesel engine as a drive source. (1) Since it has almost no mechanical drive, it can be used as a noise-free and vibration-free power generator, and is particularly effective as an emergency power source for ships. (2) Hydrogen gas fuel for power generation can be generated and stored using its own electricity in normal times, and no external replenishment is required. (3) It can be a pollution-free power generation device that produces hydrogen gas from water and returns no harmful substances to water.
