Abstract
Some embodiments of the present invention provide electrolyzer cells in which distribution of water over the surface of an electrolyte layer (e.g. a MEA) is improved. Specifically, some embodiments provide an electrolyzer cell, including a flow field plate arranged in combination with at least two porous metal layers having smooth and flat surfaces, in which water is more uniformly distributed across an active surface of an electrolyte layer, which in turn may lead to a more uniform reaction rate over the active area of the electrolyte layer. Other related embodiments also include simplifications that may reduce costs related to manufacturing and assembly of electrochemical cells.
