摘要： To provide a hydrogen generating apparatus that efficiently generates hydrogen from ammonia, and a fuel cell system that generates power using the efficiently generated hydrogen. [Solution] A hydrogen generating apparatus (1) is provided with a plasma reactor (3), a high-voltage electrode (5), a grounding electrode (7), and a gas supply means (15) that supplies a gas containing ammonia to the plasma reactor.
