    摘要： A method for controlling an amount of a liquid electrolyte in a polymer-electrolyte membrane of a fuel cell is provided. The method comprises enriching one or more of a fuel flow and an air flow with a vapor of the liquid electrolyte, the liquid electrolyte being unreplenishable via an electrochemical reaction of the fuel cell. The method further comprises delivering the vapor of the liquid electrolyte to the fuel cell including the polymer-electrolyte membrane via one or more of the gas-permeable anode and or the gas-permeable cathode. In this manner, loss of liquid electrolyte from the PEM membrane of the fuel cell can be reduced, leading to improved fuel-cell endurance.

    摘要： A fuel cell power plant (19, 19a) has a plurality of fuel cells (70, 70a, 70c) arranged in a stack (20, 20c), each fuel cell having porous, at least partially hydrophilic water transport plates (75, 81) with fuel (74) and oxidant (82) reactant gas channels, there being water channels (78, 85, 78a, 85a, 78c, 85c) exchanging water with the water transport plates. On shut down, water is retained in the water channels and water transport plates by means of either a micro vacuum pump (46), one or two valves (89, 90, 118, 120), a check valve (95, 99), capillary force in the water channels to prevent water from entering the reactant channels which, if frozen, could block flow of reactant gas upon startup.

    摘要： Embodiments are disclosed that relate to increasing a temperature in a low temperature zone in a steam reforming reactor via a radiative heating shunt. For example, one disclosed embodiment provides a steam reforming reactor comprising a reaction chamber having an interior surface, a packing material located within the reaction chamber, and a radiative heating shunt extending from the interior surface into the reaction chamber. The radiative heating shunt comprises a porous partition enclosing a sub-volume of the reaction chamber bounded by the porous partition and a portion of the interior surface, the sub-volume being at least partly free of packing material such that radiative heat has a path from the interior surface to a distal portion of the porous partition that is unobstructed by packing material.

    摘要： A fuel cell power plant assembly includes an accumulator having a housing. In one example, at least one demineralizer portion is positioned to interact with fluid within the accumulator housing. This allows for warm fluid within the accumulator housing to provide heat to the demineralizer portion. In one example, the demineralizer portion is within the housing. Another example includes a separator supported within the housing of the accumulator. A disclosed example includes a conical shaped baffle as the separator. The separator separates liquid from gas and facilitates distributing fluid flow within the accumulator housing to provide increased heat exchange with the demineralizer portion within the housing.

    摘要： A polymer electrolyte membrane (PEM) fuel cell power plant is cooled evaporatively with a water coolant system which does not permit liquid water to exit or flow through the coolant system. The coolant system utilizes a hydrophobic porous member (28) for venting gases such as fuel and/or air from a coolant water flow field in the system. Coolant water (36) is prevented from continuosly contacting the porous member during operation of the power plant thus preventing blockage of the porous member by coolant water or contaminants disposed in the coolant water.
