Abstract
A fuel processor system is provided including an autothermal reactor (ATR), a pressure swing adsorber (PSA) located downstream of the ATR, and a methanation reactor located downstream of the PSA. A method of operating of proton exchange membrane fuel cell stack involves cooling the methanator output and feeding it into the stack as an anode fuel.
