(1) Static characteristics

On both stack and single cell, the V-I characteristics were determined with parametric changes brought on such factors as temperature, pressure, fuel and air utilization, and compositions of fuel and of oxidant.

The effects on the V-I characteristics brought by changes in temperature proved to be as shown in Figs. 1 and 2, which indicate highest cell voltage to be derivable at around 73°C.
