“…Besides classic polarization curves (IV), other tools that researchers employed on WE include current interrupt, cyclic voltammetry, more visual approaches, such as electron microscopy, and electrochemical impedance spectroscopy (EIS) [10,11]. EIS is a versatile characterization technique that is already widely used in fuel cell applications [12,13] and many researchers have also implemented EIS as a tool in their investigations on PEM electrolyzers [14,15].…”

This paper investigates the influence of the cell compression of a PEM water electrolysis cell. A small single cell is therefore electrochemically analyzed by means of polarization behavior and impedance spectroscopy throughout a range of currents (0.01 A cm −2 to 2.0 A cm −2 ) at two temperatures (60• C and 80• C) and eight compressions (0.77 MPa to 3.45 MPa). Additionally, a computational model is utilized to support the analysis. The main findings are that cell compression has a positive effect on overall cell performance due to decreased contact resistances, but is subject to optimization. In this case, no signs of severe mass transport problems due to crushed transport layers are visible in either polarization curves or impedance plots, even at high currents. However, a Tafel plot analysis revealed more than one slope throughout the current range. The change in the Tafel slope is therefore discussed and connected to the electrochemical reaction or an ohmic contribution from a non-electrode component.

This investigation provides a critical analysis of the development of PEM fuel cells and related research with specific focus on the membrane material. The catalytic membrane is the most important component of the PEMFC giving rise to the need for the use of efficient, durable and cheap material to reduce the overall cost of the fuel cell. In this work, the need for materials other than Nafion to be used as PEM membranes is established and a case for the use of composite membranes material in fuel cells is made. Composite membranes increase the cell voltage by up to 11% even at high cell operating temperature of 95°C. They also increase the overall performance of the cell by up to 17% when dry hydrogen is utilised.Non-fluorinated membranes are also suitable for use in fuel cells for portable applications but they are very expensive and less conductive. Partially fluorinated membranes have good mechanical stability but expensive. The fluorinated membrane has high stability under oxidation and reduction conditions. Unfortunately, they only reach their optimum performance at ACCEPTED MANUSCRIPT 1 temperatures below 100°C which makes them of limited use in PEM fuel cells application at higher temperatures.

“…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.…”

“…The TransiEnt Library would benefit most greatly from having an accurate efficiency characterization model of an industrial electrolyzer, which authors have modelled using PEM physics in (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). include the most recent thorough review of popular papers in the characterization of electrolyzer physics and develops a detailed model of an industrial electrolyzer taking pressure, temperature, and current effects into consideration.…”

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.
