A carbon monoxide sensor in polymer electrolyte fuel cells based on symbolic dynamic filtering

Publication Type: Academic Journal

Source(s): Sensors & Actuators B: Chemical. Sep2008, Vol. 134 Issue 2, p803-815. 13p.

Abstract: Abstract: Carbon monoxide (CO) dramatically reduces the performance of a fuel cell stack if not remediated. Remediation generally requires parasitic bleeding of a small fraction (5%) of air into the fuel stream to promote oxidation of the CO and use of...
