Herein we discuss polymer electrolyte membrane (PEM) electrolysis stacks and systems we developed that are optimized for direct coupling to a photovoltaic (PV) panel. One advantage of PEM systems is their use of non-corrosive and non-toxic media. Thu

During the clamping of a Fuel Cell, the porosity of the gas diffusion layer (GDL) and the contact resistances are continuously reduced. In this work, the optimum clamping pressure is determined for three commonly used GDLs. For this purpose, polariza
