Which outcome reduces the power produced chemically when running fuel cells at cryogenic temperatures?

💡 Explanation

Reduced temperatures decrease molecular vibration, which restricts the energy available for reactions; vibrational energy transfer limits overall reaction efficiency therefore lowers chemical energy converted to electricity, rather than enhancing it like electrochemical potential improves efficiency.
