Abstract in another language

The world’s shift to alternative forms of energy production leads to the housing constructions which are independent from electricity prices and reduce CO2 emission. In the recent years, the interest in the development of proton exchange membrane fuel cells (PEMFC) in stationary application is increased. PEMFCs could supply households with electrical power using natural gas or, as a perspective, biogas. As is well known, the compound CO is undesirable in the PEMFC operating gas, as CO degrades the PEMFC by poisoning the hydrogen oxidation reaction catalyst [1, 2]. One of options to reduce the CO content to a value lower than 10 ppm is the selective methanation of CO [2, 3]. For this purpose, supported noble metal catalysts were prepared by impregnation of γ-Al2O3 spheres and screened for the selective CO methanation. A manufactured Ru/Al2O3 catalyst was selected for further investigation. The CO methanation with and without the presence of water is examined and a kinetic approach based on a Langmuir-Hinshelwood expression is suggested.
