Evaluation of simplified test rig for high throughput screening of proton exchange membrane water electrolysis components

Year: 2025

Type: article

Abstract: The research and development of components for polymer electrolyte membrane (PEM) water electrolysis are often constrained by limited test rig capacity. This study introduces a novel, compact test rig to facilitate rapid screening and extended operation of mini cells, featuring an active area of just 1.13 cm 2 . The setup can simultaneously evaluate the performance of 24 test cells, offering a simple, cost-effective, and space-saving solution. Utilizing hydrostatic pressure, the system operates without an active water supply, significantly reducing the costs and materials required for components such as porous transport layers and membrane electrode assemblies. This innovative test rig accelerates material characterization for PEM electrolyzers and supports comprehensive long-term operation studies, thereby advancing the field of electrolysis research. • Simplified and cost-effective electrochemical test system for the characterization of PEM electrolysis components. • Simultaneous electrochemical characterization of 24 cells in a single measurement cycle. • No media circulation by pumps is necessary and therefore very reliable. • Discussion of heat management at different voltages in passively heated cells. • Discussion of 500-h test run as a first reference to evaluate the setup.
