abstract = {In this study, a thermodynamic model of an active direct
methanol fuel cell (DMFC) system, which couples in‐house
experimental data for the DMFC with the mass and energy
balances for the system components (condenser, mixing
vessel, blower, and pumps), is formed. The modeling
equations are solved using the Engineering Equation Solver
(EES) program. This model gives the mass fluxes and
thermodynamic properties of fluids for each state, heat and
work transfer between the components and their surroundings,
and electrical efficiency of the system. The effect of the
methanol concentration (between 0.5 and 1.25 M) and air flow
rate (between 20 and 30 mL cm−2 min−1) on the net power
output and electrical efficiency of the system and the
condenser outlet temperature is investigated. The results
essentially showed that the highest value for the electrical
efficiency of the system is $23.6\%$ when the current
density, methanol concentration, and air flow rate are taken
as 0.2 A cm−2, 0.75 M, and 20 mL cm−2 min−1,
respectively. In addition, the air flow rate was found to be
the most significant parameter affecting the condenser
outlet temperature.},
