Abstract

The device is located between two electrodes of an electrochemical system and comprises two central parts made in the form of a closed-end bellows either side of a peripheral part, which is usually made of insulating material. The two central parts, made from electrically conducting material, are forced against the electrodes by circulating a non-conducting fluid, also acting as a coolant, at a pressure of 2-10 bars inside the space bounded by the bellows. >=1 current collecting plate is attached to the inside surfaces of the bellows with a conductor carrying the curent outside the system. A system can contain any number of the devices located between two electrodes. The system can be used in any electrochemical system in which the various components require pressure to bind them together, e.g. electrolysers, electrodialisers and especially fuel batteries of the filter-press type. The system ensures good contact between electrode elements increasing the efficiency of the electrochemical generator and the amount of current collected, whilst combining the function of a cooling channel.
