Fuel cell and electrolyte supply system
Abstract
Abstract The marginal portions of thin, sheet-like electrodes and diaphragms are pierced to form, when the diaphragms and electrodes are assembled in alternately placed stacks, ducts and channels. The end plates holding the stack of electrodes together are formed with openings and ducts interiorly of the thickness thereof to interconnect the ducts and channels through the electrode-diaphragm stack in selected hydraulic circuits. Two distinct groups of ducts are provided, one in communication with the faces of the electrodes, at alternate sides, to permit application of electrolyte charged with oxidizing, or reducing-type reactants, respectively; the other group of ducts or channels is independent of the first group and non-communicating with the first set of ducts to provide for intercommunication of the electrolyte itself.
