Shunt current in alkaline water electrolyzer
WebApplication ID: 113041. In an alkaline electrolyzer stack, all cells share the same electrolyte. As a result of all cells being in ionic contact, parasitic shunt currents flow between the cells through the manifolds and the electrolyte channels, on both the inlet and outlet side. This … WebThe principle of alkaline water electrolysis is schematically shown in Fig.3 in the example of the monopolar arrangement electrolyser. Two molecules of water are reduced to one molecule of hydrogen and two hydroxyl ions at the cathode. The hydrogen escapes from the surface of the cathode recombined in a gaseous form
