“…As for point b), the perforated electrode can offer a standardized geometry for in depth studies on the effect of multiphase ion and charge transfer typical of PEM or alkali electrolyzers electrodes. As in the present study, the complex nature of the phenomena occurring at the electrodes is often lumped into a single interface resistance of the electrode [54][55][56]. Recent modeling and experimental approaches (e.g.…”

A new-designed transparent, conductive and porous electrode was developed for application in a compact laboratory-scale proton exchange membrane (PEM) photo-electrolyzer. The electrode is made of a thin transparent quartz sheet covered with fluorine-doped tin oxide (FTO), in which an array of holes is laser-drilled to allow water and gas permeation. The electrical, morphological, optical and electrochemical characterization of the drilled electrodes is presented in comparison with a non-drilled one. The drilled electrode exhibits, in the visible region, a good transmittance (average value of 62%), a noticeable reflectance due to the light scattering effect of the hole-drilled internal region, and a higher effective surface area than the non-drilled electrode. The proof-of-concept of the applicability of the drilled electrode was achieved by using it as a support for a traditional photocatalyst (i.e. commercial TiO2 nanoparticles). The latter, coupled with a polymeric electrolyte membrane (i.e.Nafion 117) and a Pt counter electrode, forms a transparent membrane electrode assembly (MEA), with a good conductivity, wettability and porosity. Electrochemical impedance spectroscopy (EIS) was used as a very powerful tool to gain information on the real active surface of the new drilled electrode and the main electrochemical parameters driving the charge transfer reactions on it. This new electrode architecture is demonstrated to be an ideal support for testing new anodic and cathodic photoactive materials working in tandem configuration for solar fuels production by water photo-electrolysis.

“…PEM electrolyzers have been studied and modeled by several authors to date, using similar physical relationships each time with slight modifications (Abdin et al, 2015;Agbli et al, 2011;Awasthi et al, 2011;García-Valverde et al, 2012;Han et al, 2015;Lee et al, 2013;Martinson et al, 2014;Rozain and Millet, 2012;Shen et al, 2011;Zhang et al, 2012). (Olivier et al, 2017) performed a thorough study of all published research to date and compared physical expressions used in various papers.…”

In this paper a multi-physics model of a proton exchange membrane electrolyzer with selectable physics submodels is developed in Modelica R. It will be included in the open-source TransiEnt Library for future studies on the efficiency of energy storage for intermittent renewable sources and the coupling of power, gas, and heat grids. The model is derived almost explicitly from a previous research paper by (Espinosa-López et al., 2018) but uses different models for cooling system power and anode/cathode gas pressures. The model is then demonstrated in an application with wind speed records and corresponding power generation over the course of one year at a wind farm in northern Germany. It produces results similar to experimental results in other papers for use in general applications of further study.
