摘要: The reforming of methanol is acknowledged as a convenient means to generate hydrogen for PEFC due the low temperature (<280 °C) at which reaction occurs and CO content reformate. However, catalyst prone deactivation in upper range its operating temperatures. This paper presents method analysis relative changes site concentrations are deduced from series long-duration rate measurements. sites involved shown evolve independently each other. In particular, concentration adsorption decline greater than those responsible oxygenated species. A key process decrease capacity adsorb dissociate hydrogen.
