HNEI researchers investigated the effects of hydrogen contaminants on the performance and durability of hydrogen fuel cells. HNEI was part of the hydrogen quality task force (HQTF) and the work supported development of the Society of Automotive Engineers (SAE) hydrogen fuel quality standard for fuel cell vehicles, J2719. Hydrogen fuel contaminants studied included carbon monoxide, toluene,methylcyclohexane and their mixtures.
