Abstract : Electrolyte, lost from the stack to the case in a sealed electrochemical cell, is returned to the stack by a zironium oxide based ceramic deposited on the inside wall of the pressure vessel, wicking by capillary action, the electrolyte from regions external to the stack to the stack components. The ceramic wick is also used to transfer electrolyte from one separator and/or reservoir to another within the stack, replacing an interior stack wick in a recirculating design. The wall wick is also effective in a back-to-back type cell design. (Author)
