It is decided to use a direct liquid methanol fuel cell $($DMFC$)$ to produce electricity

instead of burning methanol in a power plant.

a$.$ Calculate the thermodynamic efficiency $($HHV$)$ of the DMFC$?$

b$.$ Calculate the standard cell potential for the DMFC$?($Given: F $=96500$ C$/$mol $=$

$96500$ joules$/$ volt ; $6$ electrons per methanol molecule$)$

c$.$ if the current efficiency is $100\%$ and the cell is operated at $0\mathrm{.}5$ volts calculate the

voltage efficiency? Given these efficiencies and the calculated thermodynamic

efficiency calculate the overall fuel cell efficiency?
