Water in a fuel cell accumulator is kept above freezing by a hydrogen/oxygen catalytic combustor fed hydrogen through a mechanical thermostatic valve in thermal communication with the container and connected to a hydrogen supply. The system includes an ejector hydrogen/oxygen combustor and a diffusion hydrogen/oxygen combustor for warming a medium within a container such as water in the accumulator of a fuel cell in response to a mechanic hydrostatic valve which conducts hydrogen to a combustor responsive to the temperature of the container.

Catalytic combustors keeping contained medium warm in response to hydrostatic valve

The medium (), such as water, of a container (), such as a fuel cell accumulator, is kept above freezing by a hydrogen/oxygen catalytic combustor () fed hydrogen from a source comprising a mechanical thermostatic valve () in thermal communication () with the container () and connected to a hydrogen supply (). The combustor may comprise an ejector () having hydrogen through its primary inlet () drawing air through a secondary inlet (). The combustor may comprise a diffusion combustor having a catalyst () spaced from a heating surface () and a diffusion control plate () low partial pressure of oxygen at the catalyst causing diffusion through the barrier. Water vapor from combustion condenses on a surface () and is led by hydrophilic woven carbon paper () to wicking material (), which has smaller pores than the carbon paper, which leads the water downwardly, through a disk () and plugs () to atmospheric air. The noble metal catalyst mixture includes TEFLON&#xae; to permit water generated by combustion to flow by gravity out of the catalyst.
