SYSTEMS AND PROCESSES FOR PROVIDING HYDROGEN TO FUEL CELLS

摘要

A process and system for providing a hydrogen-containing gas stream to a fue l cell anode that includes providing a hydrogen-containing gas stream that includes carbon monoxide, introducing the hydrogen-containing gas stream int o a pressure swing adsorption module that includes at least one carbon monoxid e- selective adsorbent to produce a purified hydrogen-containing gas stream, an d 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 a n internal combustion engine and a fuel cell system that utilizes fuel cell waste heat for vaporizing a hydrocarbon/water mixture.
