Professor PC Thomas Classes · Answer

$\mathrm{H}_{2}-\mathrm{O}_{2}$ fuel cell is $\mathrm{H}_{2}|\mathrm{KOH}| \mathrm{O}_{2}$ Anode : $2 \mathrm{H}_{2}+4 \mathrm{O} \overline{\mathrm{H}} ightarrow 4 \mathrm{H}_{2} \mathrm{O}+4 \overline{\mathrm{e}}$\ Cathode: $\mathrm{O}_{2}+\underline{2 \mathrm{H}_{2} \mathrm{O}+4 \overline{\mathrm{e}} ightarrow 4 \mathrm{O} \overline{\mathrm{H}}}$\ Cell reaction : $2 \mathrm{H}_{2}+\mathrm{O}_{2} ightarrow 2 \mathrm{H}_{2} \mathrm{O}$\
