Abstract:
An energy system comprising:a fuel cell stack for generating electricity from hydrogen and an oxidant to form a chemical hydride hydrogen generation system, comprising: a storage means for storing a chemical hydride solution comprising a solution of a chemical hydride solute in a solvent; a reactor containing a catalyst, for catalyzing reaction of the chemical hydride to generate hydrogen; a first pump means connected between the storage means and the reactor in a first circuit, for circulating the chemical hydride solution through the storage means and the reactor, so that the chemical hydride reacts to generate hydrogen in the presence of the catalyst; a first connection between the chemical hydride hydrogen generation system and the fuel cell for supplying hydrogen to the fuel cell; and a heat transfer circuit including second connections between the chemical hydride generation system and the fuel cell stack, for circulation of the chemical hydride solution through the fuel cell stack to effect heat transfer between the fuel cell stack and the chemical hydride solution.
