Diluents and Temperature Dependence

A further analysis was related to the effects of various diluent types and their concentration in the fuel stream in terms of their interaction with the operating temperature the experiments were done focusing on the following conditions  

The range adopted for fuel dilution depends on possible values encountered in laboratory experiments. 

The analysis was done with consideration given to the crossing effects of the two parameters. 

In Figs. 4.15,4.16,4.17, and 4.18 the effect of fuel dilution by nitrogen at fixed temperature is shown with reference to the cell current-voltage curve. 

At fixed temperature, at the imposed current the increase in dilution of the fuel with a nonreactive chemical species determines the decrease in voltage.
