The present invention relates to electrochemical cells and electrochemical systems using a one piece or unitary electrode plate hereinafter also referred to as a double electrode plate (DEP) which serves to electrically connect two adjacent cell compartments and wherein the current flow in the electrodes is parallel to the working face of the electrode. In the cell designs disclosed herein the cells are assembled as a contiguous stack of cells (cell stack) appearing similar to a filter press where the electrical connections between adjacent cells are made using the double electrode plate. In one aspect of the invention there is provided a mono-polar multiple stack electrolyser (MSE) using double electrode plates wherein the planar double electrode plates connect cells in adjacent cell stacks. The mono-polar characteristics of the cell are maintained by the presence of an air gap isolating each adjacent stack of cells connected by each double electrode plate. In another aspect of the invention there is provided a single stack electrolyser (SSE) utilizing a folded double electrode plate to connect adjacent cells in a single stack. An insulating wall separates compartments of adjacent electrode pair assemblies connected by the double electrode plate in the SSE.
