In the continuing evaluation of miniature hybrid fuel cells for controlling pressure, tests were conducted on 24 sealed assemblies consisting of a composite silver oxide-zinc cell and dual micro fuel cell assembly. The program included stand tests at both room temperature and 0/sup 0/C. Operation was on a continuous 24-hour cycle regime and a 90-minute cycle mode. The results obtained indicate that, in low gassing rate environments such as were found on the open circuit stand or on the 24-hour cycle regime, the micro fuel cells performed their function effectively in the primary mode of operation, and in high gassing rate environments such as the 90-minute cycle mode, the micro fuel cells had to be recharged in order to satisfactorily perform their function. An improved method for charging CD micro fuel cells is proposed.
