    摘要: The invention relates to a methanol-to-hydrogen cracking reactor for use with a fuel cell vehicular power plant. The system is particularly designed for rapid start-up of the catalytic methanol cracking reactor after an extended shut-down period, i.e., after the vehicular fuel cell power plant has been inoperative overnight. Rapid system start-up is accomplished by a combination of direct and indirect heating of the cracking catalyst. Initially, liquid methanol is burned with a stoichiometric or slightly lean air mixture in the combustion chamber of the reactor assembly. The hot combustion gas travels down a flue gas chamber in heat exchange relationship with the catalytic cracking chamber transferring heat across the catalyst chamber wall to heat the catalyst indirectly. The combustion gas is then diverted back through the catalyst bed to heat the catalyst pellets directly. When the cracking reactor temperature reaches operating temperature, methanol combustion is stopped and a hot gas valve is switched to route the flue gas overboard, with methanol being fed directly to the catalytic cracking reactor. Thereafter, the burner operates on excess hydrogen from the fuel cells.

    摘要: This invention relates to a fuel cell vehicular power plant. Fuel for the fuel stack is supplied by a hydrocarbon (methanol) catalytic cracking reactor and CO shift reactor. A water electrolysis subsystem is associated with the stack. During low power operation part of the fuel cell power is used to electrolyze water with hydrogen and oxygen electrolysis products being stored in pressure vessels. During peak power intervals, viz, during acceleration or start-up, pure oxygen and pure hydrogen from the pressure vessel are supplied as the reaction gases to the cathodes and anodes in place of air and methanol reformate. This allows the fuel cell stack to be sized for normal low power/air operation but with a peak power capacity several times greater than that for normal operation.

    摘要: The production of high pressure oxygen comprises the use of an electrolysis cell having an anode, a cathode, an ion exchange membrane disposed therebetween, an anode chamber, a cathode chamber and a means for regulating pressure. The cathode chamber has a porous sheet which contacts the cathode and imparts structural integrity to the ion exchange membrane. Low or ambient pressure water enters the cathode chamber, wicks through the porous sheet, contacts the cathode, and osmotically transports across the ion exchange membrane from the cathode to the anode. At the anode, water electrolysis produces hydrogen ions and oxygen. The means for regulating pressure retains the oxygen within the anode chamber until the oxygen has attained the desire high pressure. Upon attaining the desired high pressure, the oxygen is removed from the anode chamber at a rate commensurate with the production of additional oxygen. As the oxygen pressure increases within the anode chamber and as the oxygen is removed from the anode chamber, the water continues to osmotically transport across the ion exchange membrane against the pressure gradient formed by the increasing oxygen pressure.
