The cell performance is mainly determined by the cell voltage, and efforts are being made to lower the cell voltage. Factors affecting the cell voltage include the theoretical decomposition voltage required for the water decomposition reaction, the overvoltage of the catalyst electrode, and the voltage due to ohmic loss due to the electric resistance of the cell. Among them, the electric resistance of the cell is largely affected by not only the electric resistance specific to each member but also the contact resistance between the members. The contact resistance is reduced by tightening both ends of the cell with bolts or the like.
