Synergic effect investigation of carbon monoxide and other compositions on the high temperature proton exchange membrane fuel cell

Challenges and opportunities for characterisation of high-temperature polymer electrolyte membrane fuel cells: a review

“…The impact of CO and other species such as CO 2 have also been studied using DRT. 272,301 Generally, the introduction of CO and other species does not improve performance, but synergistic effects may occur when species such as H 2 O, CO 2 , and CH 3 OH are also present. However, improvements appeared to depend on current density and can be minimal.…”
