    • A PEM based water electrolysis stack consists of a number of cells connected in series by using interconnects. Water and electrical power (power supply) are the external inputs to the stack. Water supplied to the oxygen electrodes through flow fields in interconnects is dissociated into oxygen and protons. The protons are transported through the polymer membrane to the hydrogen electrodes, where they combine with electrons to form hydrogen gas. If the electrolysis stack is required to be used exclusively as an oxygen generator, the hydrogen gas generated would have to be disposed off safely. The disposal of hydrogen would lead to a number of system and safety related issues, resulting in the limited application of the device as an oxygen generator. Hydrogen can be combusted to produce heat or better disposed off in a separate fuel cell unit which will supply electricity generated, to the electrolysis stack to reduce power input requirements. This however, will add to system complexity, cost and efficiency loss. The present invention provides an improved method and a simple system for the production of oxygen, and internal utilisation of hydrogen (within the cell / stack) that also reduces the power consumption.
    • 基于PEM的水电解堆叠由许多通过使用互连串联连接的单元组成。 水和电力(电源)是堆叠的外部输入。 通过互连中的流场供应给氧电极的水分解成氧和质子。 质子通过聚合物膜传送到氢电极,在这些电极中与电子结合形成氢气。 如果电解堆叠仅需要用作氧气发生器,则所产生的氢气必须安全地排放。 氢的处理将导致许多系统和安全相关的问题,导致作为氧气发生器的装置的有限应用。 氢气可以燃烧以产生热量或更好地排放在单独的燃料电池单元中,该燃料电池单元将向电解堆叠提供产生的电力以降低功率输入要求。 然而,这将增加系统复杂性,成本和效率损失。 本发明提供了一种改进的方法和用于生产氧气的简单系统,以及内部利用氢(在电池/堆中),其也降低了功耗。

    • An electrochemical cell comprises a housing (1, 2) divided by a perforated generally horizontal plate (3) into an upper chamber (4) and a lower chamber (5). Bipolar electrodes (19, 21) are disposed in the upper chamber (4) above perforations (23) in the plate (3), between electrolyte inlet and outlet weirs (11, 13) for flowing electrolyte over the plate (3). The lower chamber (5) is a gas-supply chamber for passing a gas, e.g. propylene, up through the perforations (23), so as to bubble the gas through electrolyte (e.g. NaBr solutions) on the plate (3) and into the upper gas-collection chamber (4). A reactor may be formed by stacking several cells with their electrolyte flows in cascade. The cell is particularly suitable for electro-organic syntheses involving a gaseous reactant.
