Abstract: The invention relates to a process and an apparatus for obtaining a high-hydrogen, low-carbon-monoxide gas which is suitable for feeding low-temperature fuel cells in electric vehicles. A high-hydrogen gas mixture is generated by means of a methanol reforming reaction, using a Cu- and ZrO-containing catalyst material. The carbon monoxide content of the gas is decreased to a concentration of less than approximately 100 ppm by means of a selective methanization using a Ru- and TiO.sub.2 -containing catalyst material and/or by means of a selective oxidation using a Pt- and TiO.sub.2 -containing catalyst material.
