Abstract:
A fuel cell configured to react fuel with oxygen to generate an electric current and at least one reaction product, said fuel cell comprising:an anode flowpath configured to route said fuel through at least a portion of said fuel cell; an anode,in fluid communication with said anode flowpath and upon which a catalytic reaction with said fuel is configured to take place; a cathode flowpath configured to route said oxygen through at least a portion of said fuel cell; a cathode in fluid communication with said cathode flowpath and upon which a catalytic reaction with said oxygen is configured to take place; a membrane disposed between said anode and said cathode such that electrolyte communication is established therebetween during operation of said fuel cell; and at least one coolant flowpath fluidly decoupled from said anode flowpath and said cathode flowpath, wherein said coolant flowpath defines a coolant isolation manifold, and wherein said coolant isolation manifold includes a fluid dielectric coolant, said fluid dielectric coolant comprising a kerosenic hydrocarbon.
