It serves to test components for hydrogen production by alkaline and anion exchange membrane electrolysis. The cell has an active area of 5 cm², a serpentine flow field made of nickel, with the necessary connections for fluids, current and voltage, as well as connections for temperature measurement and heating.German Federal Ministry of Education and Research (BMBF)03KZZ0704AGerman Federal Ministry of Economic Affairs and Climate Action (BMWK)3EI3011A
