The heat generated by the chemical reactions

The fuel gases in the anode gas channel consist of CH4, H2, H2O, CO and CO2, while the air in the cathode gas channel comprises O2 and N2. All the gases are considered as ideal gases. During the analysis, the inlet velocity in the two gas AWD 131-138 is assumed to be 4 (m s−1) so that it can be regarded as a laminar flow. The operating temperature and pressure are assumed as 1073 K and 1 atm.
