摘要： The anodes of fuel cells in a fuel cell stack are passivated during no load, hot-hold periods by directing a stream of desulfurized natural gas through the anode side of the cells in the stack. The cell voltage is thus maintained below 800 millivolts, preferably between 300 and 500 millivolts, during such periods.

摘要： Adjustment of the noble metal catalytic activity in the production of noble metal alloyed catalyst preparation using alloying metals capable of multiple valence states improves the alloying metal loading. A noble metal is precipitated from a liquid onto a support. Prior to the addition of an alloying metal which is capable of a low valence state having low solubility and a high valence state having high solubility, the catalytic activity of the noble metal precipitate is reduced. Reduction is accomplished by adjusting the temperature and/or pH of the liquid such that a minimal amount of the alloying metal will be converted from the lower to the higher valence state. By maintaining the alloying metal in the lower valence state, a greater amount of the alloying metal which has been dissolved into the liquid is precipitated onto the support, thereby attaining high loadings, reducing waste of the alloying metal, making the loadings predictable, and making the waste liquid more environmentally sound.

摘要： A support plate for a proton exchange membrane fuel cell includes a porous support body that has a central portion and a peripheral portion integral with and circumferentially completely surrounding the central portion, and a sealing body of elastomeric sealing material that completely fills the pores of the peripheral portion to make it impermeable to fluids. The support plate may be assembled with another one and with a proton exchange membrane interposed between the two support plates to form an assembly, and the sealing body then peripherally joins and seals the assembly and fills any gaps that may be present between the peripheral portions due to the absence of the membrane from such regions and thus to peripherally encapsulate the membrane.

摘要： An internally cooled proton exchange membrane fuel cell device includes a fuel cell including a pair of substantially coextensive electrode components each of which includes a porous central region and a fluid-impermeable peripheral region circumferentially completely surrounding the central region, and a proton exchange membrane component interposed between at least the central regions of the electrode components. The fuel cell device further includes an arrangement for cooling the fuel cell, including at least one enclosed cooling channel situated at the peripheral region of one of the electrode components and supplied with fresh cooling medium, with the spent cooling medium being discharged from the cooling channel. There is further provided a heat transfer device that is operative to transfer heat from the central region to the peripheral region of the one electrode component. This heat transfer device advantageously includes a hermetically sealed casing and, within the casing, a quantity of a heat transfer substance of the type that evaporates at temperatures below those reached by a central zone of the casing during the operation of the fuel cell and condenses at temperatures above those prevailing at a peripheral zone of the casing during the operation of the cooling arrangement.

摘要： Cross-over leakage in fuel cells is determined by comparing the concentration of carbon dioxide in the oxidant inlet stream and cathode effluent. The amount of carbon dioxide in the oxidant stream of a fuel cell should remain constant, barring leakage problems. Therefore, if the carbon dioxide concentration changes, a leakage problem exists. Since this process is in-line, the staff operating the fuel cell stack is virtually immediately alerted to a potential leakage problem.

摘要： Pressure differential 6 between cathode 2 and anode 3 is controlled by valve 24, 26 of valve complex 20. The complex 20 is located within anode recirculation loop 8, 9, 3, 20 whereby controllability is not lost with no flow through the anode. Control is thereby retained during nitrogen purging of the cathode.An orifice 22 in the valve complex 20 precludes accidental full closure of the complex, and is selected to avoid immediate damage to the fuel cell on such closure.
