Secondary Battery Type Fuel Cell System

摘要

This secondary battery type fuel cell system is provided with a hydrogen generator (1) that generates hydrogen by an oxidation reaction with water and is capable of regeneration by a reduction reaction with hydrogen and a SOFC (5) having an electricity generating function and a water electrolysis function. The system circulates a gas containing hydrogen and water vapor between the hydrogen generation part (1) and SOFC (5). Also provided is a water vapor partial pressure ratio setting section (heater (2), temperature sensor (3), and controller (7)) that sets the water vapor partial pressure ratio for the hydrogen generator (1).

1. A secondary battery type fuel cell system, comprising:
a hydrogen generation section that generates hydrogen by an oxidation reaction with water and is capable of being regenerated by a reduction reaction with hydrogen; and
a power generation/electrolysis section havinga power generation function of generating power by using hydrogen supplied from the hydrogen generation section as a fuel, andan electrolysis function of electrolyzing water to generate hydrogen to be supplied to the hydrogen generation section,whereingas containing hydrogen and water vapor is made to circulate between the hydrogen generation section and the power generation/electrolysis section, andthe secondary battery type fuel cell system further comprises a water vapor partial pressure ratio setting section that sets water vapor partial pressure ratio of the hydrogen generation section.
