The PEM water electrolysis technology is considered as an important bridge to a sustainable hydrogen economy, especially when coupled with renewable energy sources. The establishment of this technology is however, limited by the high costs of components and balance of plant. We propose a design concept adapted to operating pressures of up to 30 bars and incorporating cost effective, as well as mechanically and chemically stable stack components. With this advanced design, hydrogen can be efficiently produced from renewable energy sources, while meeting a cost target of 2500 €/Nm³h with a production volume of 100 stacks. Fraunhofer ISE is open for discussion on any kind of activities involving PEM water electrolysis, from components development and characterization to stack and system design.
