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

Figure 13

The effect of the fuel cell operating pressure, P (atm), on the polarization curve for a direct propane fuel cell (DPFC) model at 150°C. The values of P (atm) for the above three cases ( = 0.9/0.1) were represented by the following symbols: (i) open circles: 11 atm, (ii) open triangles: 3 atm, and (iii) solid diamonds: 1 atm (reference case). All the other parameters were the same as the reference case mentioned in Table 1.
