    • A system for modulating a temperature of one or more fuel cells in a fuel cell stack includes a catalytic combustor in heat exchange relationship with the fuel cell stack. The catalytic combustor promotes an exothermic reaction. A hydrogen source selectively supplies hydrogen (H2) to the catalytic combustor. The H2 reacts with oxygen (O2) in the exothermic reaction. In one feature, the catalytic combustor lies adjacent to the fuel cell stack and includes a series of catalyst coated flow channels. In another feature, the catalytic combustor includes a plate having a catalyst layer and that is offset from the fuel cell stack. Heat to radiates from the catalytic combustor to the fuel cell stack. In still another feature, a jacket encloses the fuel cell stack to form a gap between the jacket and the fuel cell stack through which hot exhaust from the catalytic combustor circulates.
    • 用于调制燃料电池堆中的一个或多个燃料电池的温度的系统包括与燃料电池堆热交换关系的催化燃烧器。 催化燃烧器促进放热反应。 氢源选择性地向催化燃烧器供应氢(H 2 H 2)。 在放热反应中,H 2 O与氧(O 2 H 2)反应。 在一个特征中,催化燃烧器邻近燃料电池堆并且包括一系列催化剂涂覆的流动通道。 在另一特征中,催化燃烧器包括具有催化剂层并且偏离燃料电池堆的板。 从催化燃烧器辐射到燃料电池堆的热量。 在另一个特征中,护套封闭燃料电池堆,以在护套和燃料电池堆之间形成间隙,通过该间隙,来自催化燃烧器的热排气循环通过。
