Modeling and Analysis of Static Water Feed Solid Polymer Water Electrolysis Cell

Abstract:

A simple model specific to static water feed solid polymer electrolyte (SPE) water electrolysis cell is constructed containing Butler-Volmer equation for calculating electrode over potentials, Nernst equation for calculating thermodynamic voltage and water balance equation for solving membrane water content. Based on the model, the water content distribution of the membrane is obtained, and the operating current density limitation is shown. It is indicated that the operating current density limitation of static water feed SPE electrolysis cell is obviously lower than that of normal SPE electrolysis cell.
