This document describes a method for enhancing bubble evacuation in electrochemical systems by integrating flow channels into porous electrode materials. These channels are engineered during the manufacturing process using techniques such as phase separation micro molding or sacrificial molds. The flow channels facilitate forced electrolyte flow, improving mass transport and preventing gas bubble accumulation, which can block active catalyst sites. This method also mitigates gas crossover risks, optimizes electrode performance, and contributes to system reliability and longevity. The porous electrode materials with integrated flow channels can be used in electrochemical cells to increase the electrochemical active surface area and are applicable in membrane electrode assemblies and alkaline water electrolyzers.
