Abstract:
1. A system for maintaining hydrogen purity in an electrical generator, the system comprising: a hydrogen generator; a hydrogen cooled electrical generator, said electrical generator fluidly coupled to receive hydrogen gas from said hydrogen generator by a gas conduit; a vent line having a first and second end, said first end being directly fluidly coupled to said electrical generator and said second end being fluidly coupled to the atmosphere; a valve coupled to said vent line between said hydrogen cooled generator and said vent line second end; a hydrogen purity monitor operably coupled to said electrical generator and said valve, said hydrogen purity monitor including means for transmitting a signal to said valve; and, a pressure transducer fluidly coupled to said conduit, said pressure transducer transmitting a signal to said hydrogen generator in response to the gas pressure in said electrical generator falling below a first threshold wherein said hydrogen generator produces hydrogen gas in response to said pressure transducer signal, wherein said valve operates to release hydrogen gas directly from said electrical generator to the atmosphere in response to a signal from said hydrogen purity monitor.
