1. A fuel cell system comprising:
a fuel cell having a housing and a fuel cell stack positioned in the housing, the fuel cell stack being configured to produce an electrochemical reaction from a fuel and air to output electricity;
a fuel system having a fuel source, a fuel vaporizer, and fuel lines through which the fuel flows from the fuel source to the fuel vaporizer and from the fuel vaporizer to the fuel cell stack; and
a second fuel tank and a regulator arranged between the secondary fuel tank and the fuel cell stack, wherein the fuel source is a first fuel tank, and the regulator is selectively operated to control flow of the fuel from the secondary fuel tank to the fuel cell stack;
wherein the fuel vaporizer includes a conductive tube through which the fuel flows, the conductive tube being in contact with the housing to conduct heat from the housing to the fuel to vaporize the fuel; and
wherein the flow of the fuel from the first fuel tank through the fuel vaporizer to the second fuel tank is controlled by operating the regulator.
