A process and a device for generating electricity by means of a fuel battery are described, comprising a start-up phase of said battery, and a steady-state operation of said battery, during which said battery, supplied with a hydrogen gas, produces electricity and heat. According to said process, for its start-up, said battery is supplied with a hydrogen gas, containing a volume of at least 70% hydrogen, generated by self-sustained combustion of at least one solid pyrotechnic load hydrogen gas generator; and during its steady-state operation, said battery is supplied with a hydrogen gas, generated by thermal decomposition of at least one solid load hydrogen gas generator; a portion of the heat produced by said battery during operation being transferred to said at least one solid load for start-up and maintenance of its thermal decomposition. |
