14 W 07 V 20 A

50 cm2 Hydrogen, simulated reformate gas Air

Table 2 Conditions commonly adopted for all tests

Temperature

73°C (346 K)

Pressure

0.2 MPa abs.

Fuel utilization

75% at 400 mA/cm2

Air utilization

25% at 400 mA/cm2

(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.
