An Improved Tank in Series Model for the Direct Methanol Fuel Cell

Figure 4

Histograms with steady-state simulation results predicted by TSR model for DMFC with coflow mode of fuel and oxidant (𝐸_cell=0.2V). Numerical modelling of fuel cell with anode 1.5 M feed of fuel and pure oxygen feed at the cathode. Temperature variation 𝛿𝑇^{𝑆𝑖,𝑗}=𝑇^{𝑆𝑖,𝑗}−𝑇^𝐶_in. Methanol molar concentration variation 𝛿𝐶^MeOH_𝑖,𝑗=𝐶^MeOH_𝑖,𝑗−𝐶^MeOHin. Carbon dioxide molar concentration variation 𝛿𝐶^CO2_𝑖,𝑗=𝐶^CO2_𝑖,𝑗−𝐶^CO2_in.
