This patent describes a repeating component within an electrochemical cell stack comprising: (a) means forming a flat fuel cell electrolyte matrix; (b) a flat porous fuel cell electrolyte reservoir plate batting the fuel cell electrolyte matrix and operable to draw and store product water from the fuel cell electrolyte matrix when the stack is operating in a fuel cell mode; (c) a flat porous electrolysis cell electrolyte reservoir plate adjacent to the fuel cell electrolyte reservoir plate; (d) means forming a flat electrolysis cell electrolyte matrix abutting the electrolysis cell electrolyte reservoir plate, the latter being operable to draw water from the fuel cell electrolyte reservoir plate to the electrolysis cell electrolyte matrix for consumption when the stack is operating in an electrolysis cell mode; (e) a first formed metallic separator plate adjacent to the fuel cell electrolyte matrix; (f) a first flat current conductor plate adjacent to and in contact with the first formed plate; (g) a first insulating sheet adjacent the first conductor plate; (h) a second formed metallic separator plate adjacent to the electrolysis cell electrolyte matrix; (i) a second flat current conductor plate adjacent to and in contact with the second formed plate; (j) a second insulating sheet adjacent the second conductor plate; and (k) a flat cooling plate adjacent at least one of the insulating sheets.
