An inexpensive dielectric coolant for fuel cell stacks. The present invention is directed to a fuel cell, a fuel cell system, and methods for cooling a fuel cell and fuel cell system. The fuel cell is configured to react fuel with oxygen to generate an electric current and at least one reaction product and comprises an anode, an anode flowpath, a cathode, a cathode flowpath, and a membrane disposed between the anode and the cathode. At least one coolant flowpath is fluidly decoupled from the anode and cathode flowpaths and d fines a coolant isolation manifold. The coolant isolation manifold includes a fluid dielectric coolant that comprises a kerosenic hydrocarbon, which can be kerosene or an emulsion of water in kerosene. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 C.F.R. §1.72(b). |
