Analysis of the Flow-Through Porous Trielectrode Reactor

The limiting current analysis has been applied to a flow-through porous electrode with two counterelectrodes. Theelectric driving force variation through the working electrode can be minimized by adjusting the fraction of the total currentthat passes through each counterelectrode. For applications with a maximum acceptable ohmic potential drop in the reactor,the use of two counterelectrodes can substantially increase the maximum processing rate for a flow-through reactorand hence make it more competitive with the flow-by electrode configuration.
