An electrochemical cell has a membrane located between two flow field plates. On a first side of the membrane, there is a porous support surrounded by a seal between the membrane and the flow field plate. There is a gap between the porous support and the seal at the surface of the membrane. On a second side of the membrane, there is a seal between the membrane and the flow field plate located inside of the gap in plan view. The electrochemical cell is useful, for example, in high pressure or differential pressure electrolysis in which the second side of the membrane will be consistently exposed to a higher pressure than the first side of the membrane.

High or differential pressure electrolysis cell

An electrochemical cell has first and second flow fields on opposite sides of a membrane. The first flow field has a set of generally linear channels in which the flow of a fluid in the field is contained between parallel elongate ridges. The second flow field is defined by a set of parallel discontinuous ridges. Preferably most ridge segments in the second flow field are oblique, for example perpendicular, to and overlap with two or more ridges of the first flow field. The flow fields may be used in, for example, water electrolysis cells including high or differential pressure polymer electrolyte membrane (PEM) electrolysis cells.
