Abstract (en)
[origin: CA3225562A1] The invention relates to an electrolytic cell for polymer electrolyte membrane electrolysis with a cathode half-cell and an anode half-cell, the cathode half-cell and the anode half-cell being separated from one another by means of a polymer electrolyte membrane. The cathode half-cell has a first catalyst material designed to catayse a reduction of molecular oxygen, and a second catalyst material designed to catalyae a reduction of hydrogen ions. The first catalyst material is introduced into a first catalyst layer and the second catalyst material is introduced into a second catalyst layer different from the first catalyst layer, the first catalyst layer being disposed directly adjacent to the second catalyst layer. The invention also relates to a method for producing an electrolytic cell for polymer electrolyte membrane electrolysis.
Abstract (de)
Es wird eine Elektrolysezelle (1) zur Polymerelektrolytmembran-Elektrolyse mit einer kathodischen Halbzelle (2) und einer anodischen Halbzelle (3) angegeben, wobei die kathodische Halbzelle (2) und die anodische Halbzelle (3) mittels einer Polymerelektrolytmembran (4) voneinander getrennt sind. Die kathodische Halbzelle (2) weist ein erstes Katalysatormaterial (5), ausgebildet zur Katalyse einer Reduktion von molekularem Sauerstoff, auf.Daneben wird ein Verfahren (100) zur Herstellung einer Elektrolysezelle (1) zur Polymerelektrolytmembran-Elektrolyse angegeben.
