Abstract
This thesis models a proton exchange membrane photoelectrochemical cell (PEM PEC), which, with the aid of illumination, electrolyzes water and produces hydrogen and oxygen gas. The homogenized, one-dimensional model tracks proton concentration as well as electric potential across the width of the cell, which is comprised of three layers; a porous anode catalyst layer, at which the electrolysis reaction occurs, a proton exchange membrane layer, serving as a solid electrolyte, and and porous catalyst layer, at which the hydrogen gas is produced. Model parameters, including deviations from electroneutrality in the membrane and drift strength, are investigated, along with physical variations, including temperature, water content, and size adjustments. Additionally, electrical parameters, such as light intensity and applied current are varied. The largest improvement in cell performance occurs when the electrode lengths increase. The second being an increase in light intensity. The most detrimental effects on the cell are greater 'pore sizes' in the electrodes, followed by reducing both water contents and operating temperatures.
