Engineering Quarterly Review

Abstract

To demonstrate the technology of oxygen extraction from seawater by designing an underwater vehicle powered by a fuel cell and oxygen supplied by Aquanautics system. Major improvements were achieved in the power output relationship of the electrochemical cell. A tenfold increase in output (from 0. 15 1 sq. cm 2 of cell to 1.5 1 sq. m) at a given power input (100 watt-min/1). See attached figure. This has been due to: 1) use of higher conductivity carrier solution 2) use of electrocatalysis (see John Kerr's report) 3) optimization. Oxygen produced at such operating conditions has been used in an Al-O2 fuel cell in a small-scale integration.
