Furthermore, it is possible to improve the inherent disadvantage of the PEFC itself that the self-sustained operation function does not work when a power failure occurs when power generation is stopped due to full storage.
  • "a” and “b” may be adjusted according to the type of source gas so that the number of thermal environment points increases. For example, if hydrogen, which does not emit carbon dioxide, is used as the raw material gas, no greenhouse gas is generated, so a further environmental value may be added to the thermal environment point.
