A process and system for providing a hydrogen-containing gas stream to a fuel cell anode that includes providing a hydrogen-containing gas stream that includes carbon monoxide, introducing the hydrogen-containing gas stream into a pressure swing adsorption module that includes at least one carbon monoxide- selective adsorbent to produce a purified hydrogen-containing gas stream, and introducing the purified hydrogen-containing gas stream to the fuel cell anode. The pressure swing adsorption module can also include a second adsorbent and/or catalyst. Also disclosed is a fuel cell system coupled to an internal combustion engine and a fuel cell system that utilizes fuel cell waste heat for vaporizing a hydrocarbon/water mixture.
L'invention concerne un procédé et un système permettant d'alimenter un flux gazeux renfermant de l'hydrogène dans l'anode d'une pile à combustible. Le procédé consiste à utiliser un flux gazeux renfermant de l'hydrogène et comprenant du monoxyde de carbone, à introduire celui-ci dans un module d'adsorption modulée en pression comprenant au moins un adsorbant sélectif de monoxyde de carbone permettant de produire un flux gazeux renfermant de l'hydrogène purifié et à introduire celui-ci dans l'anode de la pile à combustible. Le module d'adsorption modulée en pression peut également comprendre un second adsorbant et/ou catalyseur. L'invention concerne également un système de pile à combustible couplé à un moteur à combustion interne et un système de pile à combustible mettant en oeuvre de la chaleur perdue de la pile à combustible, en vue de vaporiser un mélange hydrocarbone/eau.
