  • HEATER AND METHOD OF OPERATING
    Publication number: 20150064591
    Abstract: A heater includes a heater housing extending along a heater axis. A fuel cell stack assembly is disposed within the heater housing and includes a plurality of fuel cells which convert chemical energy from a fuel into heat and electricity through a chemical reaction with an oxidizing agent. An electric resistive heating element is disposed within the heater housing. A positive conductor is disposed within the heater housing and is connected to the fuel cell stack assembly and to the electric resistive heating element and a negative conductor is connected to the fuel cell stack assembly and to the electric resistive heating element. The electric resistive heating element is arranged to elevate the fuel cell stack assembly from a first inactive temperature to a second active temperature.
