At a constant load
of 10 A, the cell needs hydrogen to be supplied to the anode at
a rate of 96 ml/min; air must be supplied at a rate of 299 ml/
min. The cell voltage exhibited a stable value of approximately
0.73 V at 10 A for 13 min. However, the cell voltage
decreased to 0.4 V after 12 min and then dropped to 0 V.
