      abstract     = {One of the major challenges of metal-air batteries is the
                      impeded oxygen reduction reaction (ORR) during discharge
                      occurring at the gas diffusion electrode (GDE) of the
                      battery. Due to the impeded ORR, high overpotentials emerge
                      and result in a loss of energy efficiency. In order to
                      improve the latter, suitable catalysts have to be employed.
                      Transition metal oxides like manganese oxides (e.g., MnO2,
                      Mn2O3, Mn3O4, Mn5O8, MnOOH) [1,2] are known as good and
                      inexpensive materials for the ORR in alkaline media. A
                      drawback of manganese oxide catalysts is the poor electrical
                      conductivity. Hence, the approach presented in this work
                      aims to enhance the catalytic activity of Mn3O4 and
                      γ–MnO2 by the incorporation of conductive carbon material
                      into the pure manganese oxide. The resulting hybrid
                      catalysts are prepared either by impregnation of Super C 65,
                      Vulcan XC 72, and Kuraray YP 50F via a sol-gel technique
                      employing a MnO2 precursor sol or by direct precipitation of
                      Mn3O4 or γ–MnO2 particles in the presence of the carbon
                      materials mentioned above. Investigations by rotating disc
                      electrode (RDE) show a noticeably higher catalytic activity
                      of the hybrid catalysts than for the pure materials. For
                      verification of the results measured by RDE, screen printed
                      GDEs are prepared and tested in Zn-air full cells.},
