An Investigation of Direct Hydrocarbon (Propane) Fuel Cell Performance Using Mathematical Modeling

Figure 7

The effect of the membrane layer proton conductivity, (S/m), on the polarization curve for a direct propane fuel cell (DPFC) model at 150°C and 1 atm. The values of (S/m) for the above three cases were represented by the following symbols: (i) open triangles: 1x10²⁰ S/m, (ii) solid diamonds: 5 S/m (reference case), and (iii) open circles: 1x10⁻⁴ S/m. All the other parameters were the same as the reference case mentioned in Table 1.
