Abstract: A method for producing a synthesis gas including carbon monoxide and hydrogen comprises a number of steps. In particular, the method comprises: a) providing a feedstock gas comprising methane and carbon dioxide, b) converting the feedstock gas into an intermediate product gas comprising carbon dioxide and water vapor and c) converting the intermediate product gas obtained in step b) into the synthesis gas comprising carbon monoxide and hydrogen by means of electrolysis. The synthesis gas including carbon monoxide and hydrogen can be obtained from biogas with particularly high efficiency by means of the described method and an appropriate apparatus. To this end, the conversion of the biogas in a fuel cell is coupled with co-electrolysis in an electrolysis cell.

Abstract: A material for an electrode, the material for as well as a method of making the material for an electrode comprising or consisting of a compound of formula (1) M2Ni1?xCoxO4+? and/or of formula (2) La1?yMyNi1?xCoxO4+? where M represents Pr and/or Nd, 0.0?x?0.2, 0.25???0.3 and 0<y?10 0.5.

Abstract: The invention relates to a method for producing carbon monoxide, comprising the following steps: a) humidifying an educt gas containing carbon dioxide with water, b) supplying the humidified educt gas from step a) into an electrolytic cell (1), and c) electrolyzing the humidified educt gas supplied according to step b) in the electrolytic cell (1) such that the carbon monoxide is obtained. With the described method and with the described device (12), carbon monoxide can be produced via CO2 electrolysis with particularly high efficiency. This is achieved with the educt gas containing carbon dioxide being humidified before the electrolysis.
