Abstract Porous gas‐diffusion electrodes (GDEs) are widely used in electrochemical applications where a gaseous reactant is converted to a target product. Important applications for silver‐based GDEs are the chlor‐alkali and the CO2 electrolysi

For proton exchange membrane water electrolysis (PEMWE) to become competitive, the cost of stack components, such as bipolar plates (BPP), needs to be reduced. This can be achieved by using coated low-cost materials, such as copper as alternative to

Abstract Fe‐N‐C catalysts are a promising alternative to replace cost‐intensive Pt‐based catalysts in high temperature polymer electrolyte membrane fuel cell (HT‐PEMFC) electrodes. However, the electrode fabrication needs to be adapted for

Bereits im vergangenen Jahr bestand Konsens, dass Wasserstoff (H2) als Energieträger der Zukunft gesehen wird, der die fluktuierende Stromerzeugung aus erneuerbaren Energien zugänglich machen und die Energieversorgung vieler Sektoren dekarbonisiere
