Abstract :
Experimental data have been generated on an Eagle-Picher 50 Ah, IPV Ni-H2 cell under various test conditions. These conditions included discharges and charges at different rates and temperatures, in order to determine the effect of these on the charge and discharge efficiencies of the Ni-H2 cell. Such a database, hither to not available in the literature, should provide considerable support to the modeling effort in terms of identifying appropriate values for the model parameters. The charge behavior points to an interesting possibility of examining the multiple phases of the positive electrode active material. These studies have been augmented by simulations from our mathematical model
