      abstract     = {In this work, a catalyst coated-diaphragm (CCD) for
                      classical alkaline electrolysis was prepared by the
                      blade-coating method, using Raney nickel as HER catalyst and
                      a Zirfon® (AGFA Perl UTP 500) diaphragm. Our best CCD
                      reduced the overvoltage in an alkaline single cell by 270 mV
                      at 300 mA cm−2 compared to the benchmark, mainly due to
                      the higher catalytic activity and surface area of the Raney
                      nickel electrode. The new electrode system also showed a low
                      degradation rate of 22 μA cm−2 h−1 after 1000 h at a
                      cell voltage of 2 V. The gas purity tests showed that the
                      CCD has hydrogen in oxygen contamination well below the
                      lower explosion limit, even at low current densities.
                      Therefore, we propose the use of our novel CCD architecture
                      for atmospheric alkaline electrolyzers, which have a partly
                      separated electrolyte cycle},
