Abstract:
1. An arrangement for generating hydrogen gas comprising: (a) a catalyst chamber comprising a catalyst; (b) a fuel chamber connected to the catalyst chamber, the fuel chamber being configured to store a reactant material comprising a borohydride capable of generating hydrogen gas when contacting said catalyst; (c) a spent fuel chamber connected to the catalyst chamber, the spent fuel chamber being configured to receive borate and hydrogen gas, the borate and the hydrogen gas being generated by contacting the borohydride and the catalyst, the spent fuel chamber being further configured to retain the borate separate from the reactant material; (d) a gas conduit in direct communication with the spent fuel chamber and with the fuel chamber, the conduit including a check valve, the check valve being configured to allow unidirectional flow of hydrogen gas; and (e) a hydrogen gas outlet conduit connected to the gas conduit.
