    摘要： A solid oxide fuel cell power generation system's entire output is made up of three streams: water, sequestered carbon dioxide provided into a storage tank, and carbon dioxide depleted air. Thus, the system generates electricity from a hydrocarbon fuel, while outputting substantially no pollutants into the atmosphere and cleaning the air by removing carbon dioxide from the air exhaust stream. Thus, the system outputs cleaner air than it takes in without releasing pollutants into the atmosphere, while generating electricity from a readily available hydrocarbon fuel, such as natural gas.

    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.

    摘要翻译： 生产高压氧气包括使用具有阳极，阴极，设置在其间的离子交换膜，阳极室，阴极室和用于调节压力的装置的电解池。 阴极室具有与阴极接触并赋予离子交换膜结构完整性的多孔片。 低或环境压力的水进入阴极室，穿过多孔片，与阴极接触，并渗透离子交换膜从阴极传输到阳极。 在阳极处，水电解产生氢离子和氧气。 用于调节压力的装置将氧气保持在阳极室内，直到氧气达到期望的高压。 达到所需的高压后，氧气以与额外的氧的产生相称的速率从阳极室去除。 当氧气压力在阳极室内增加时，并且随着从阳极室中除去氧气，水依靠增加的氧气压力形成的压力梯度继续渗透离子交换膜。
