Abstract : In 1988, AEL was awarded a Small Business Innovation Research (SBIR) Phase I contract on Navy Topic N88-94 by the NAVSEA R&D Officer, Code 03R. In 1990, this topic moved to Phase II with a contract involving the lab demonstration of the use of diesel type fuel in high temperature molten carbonate or Direct Fuel Cells (DFCs). The Phase II work was successfully completed in 1992. In 1995, Navy Code 03R agreed to transfer Topic N88-94 to the USCG R&D Office, G-SIR. The Phase III Feasibility Study was awarded to AEL in 1996 to perform the work described in this report. The USCGC VINDICATOR (WMEC-3) has been evaluated as the candidate ship for fuel cell repowering at 2.58 MW. It is a former T-AGOS ship with diesel-electric propulsion and ship's service. The four 600 kW diesel generators (2.4 MW) would be replaced with twelve 215 kW DFC one-sided-fit fuel cell modules embodying a 'no-maintenance' rapid changeout approach. The repowered ship would be faster, consume half of the fuel for the equivalent range, be super-quiet, be air pollution-free, cut the crew complement and produce potable water onboard as a byproduct. The study evaluated technical aspects of fuel cells, naval architectural removals and additions, maintenance, risk and cost-effectiveness issues. The use of electric utility type DFCs, with the cost reduction and mass production advantages of this on-land marketplace will make possible early introduction of marine-derivative fuel cell power plants for ship applications. It is concluded that repowering ships with fuel cells is feasible and that the next step is a Preliminary Design.
