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.</abstract><sumDscr/></stdyInfo><method><dataColl><sources/></dataColl><anlyInfo/></method><dataAccs><setAvail/><useStmt/></dataAccs><othrStdyMat><relPubl><citation><titlStmt><IDNo agency="doi">10.1016/j.ijhydene.2021.11.068</IDNo></titlStmt><biblCit>C.
