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

Figure 2

The effect of progressive and nonprogressive time-stepping loops on the polarization curve for a direct propane fuel cell model (DPFC) at 150°C and 1 atm. The above two cases were represented by the following symbols: (i) open circles: model without a progressive time-stepping loop, and (ii) solid diamonds: model with a progressive time-stepping loop.
