APPARATUS AND METHODS FOR OPERATING FUEL CELLS IN COLD ENVIRONMENTS

摘要

This disclosure relates to apparatus and methods for managing water and heat produced by a fuel cell in cold environments. The apparatus can include an enclosure for surrounding the fuel cell or fuel cell unit. Excess water produced by the fuel cell can be disposed of in such a way it does not interfere with system operation. The apparatus can comprise a tube connected to an outlet of the fuel cell or fuel cell unit to collect water and can lead into a chamber. A second tube can lead from the chamber to the outside of the enclosure to allow venting. Vapour from the fuel cell that condenses or freezes can be held within the container such that it does not block the fuel cell outlet. The apparatus can also comprise a heat exhaust structure to direct heat from the fuel cell toward the chamber.
