Abstract: A heater includes a heater housing extending along a heater axis; a fuel cell stack assembly disposed within the heater housing and having 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 disposed within the heater housing and electrically connected to the fuel cell stack assembly; and a first thermal switch located between the fuel cell stack assembly and the electric resistive heating element. The first thermal switch is closed to place the fuel cell stack assembly in electrical communication with the electric resistive heating element when the fuel cell stack assembly is electrochemically active and is open to prevent electrical communication between the fuel cell stack assembly and the electric resistive heating element when the fuel cell stack assembly is not electrochemically active.

Abstract: A fuel cell stack includes a plurality of fuel cell cassettes each including a fuel cell with an anode and a cathode. Each fuel cell cassette also includes an electrode interconnect adjacent to the anode or the cathode for providing electrical communication between an adjacent fuel cell cassette and the anode or the cathode. The interconnect includes a plurality of electrode interconnect protrusions defining a flow passage along the anode or the cathode for communicating oxidant or fuel to the anode or the cathode. An electrically conductive material is disposed between at least one of the electrode interconnect protrusions and the anode or the cathode in order to provide a stable electrical contact between the electrode interconnect and the anode or cathode. An encapsulating arrangement segregates the electrically conductive material from the flow passage thereby, preventing volatilization of the electrically conductive material in use of the fuel cell stack.

Abstract translation: 燃料电池堆包括多个燃料电池盒，每个燃料电池盒包括具有阳极和阴极的燃料电池。 每个燃料电池盒还包括与阳极或阴极相邻的电极互连件，用于在相邻的燃料电池盒和阳极或阴极之间提供电连通。 互连包括多个电极互连突起，其限定沿着阳极或阴极的流动通道，用于将氧化剂或燃料连接到阳极或阴极。 导电材料设置在至少一个电极互连突起和阳极或阴极之间，以便在电极互连和阳极或阴极之间提供稳定的电接触。 封装装置将导电材料与流动通道隔离，从而防止在使用燃料电池堆时导电材料的挥发。
