Abstract:

This report summarizes the work carried out in the DARPA Phase IV program for the Aquanautics Gill Technology during the period from October 1, 1987 through September 30, 1988. This report provides details of the three areas where major technological progress was achieved Carrier chemistry , Electrochemical carrier kinetics, Scale-up and cell improvements. The self- propelled demonstration vehicle was designed and most of the hardware procured. The testing of individual items was essentially completed. The highlight of the demonstration vehicle program was the small scale integration of the fuel cell and oxygen extraction unit EOC. The integration process went very smoothly and all the design specification were met. The fuel cell generated 18W and the EOC was operated at 4W. The focus of the program was expanded to include ocean-floor stationary power design. A conceptual design of the power system has been carried out. The design involves in-situ hydrogen generation from aluminum, oxygen extraction from seawater and direct feed of the Aquanautics carrier to a fuel cell. Keywords Fuel cells Power generation Oxygen generators.
