PEM Fuel Cell for Replacement of Submarine/Battery Diesel Generator Emergency Power

Eighty tons of weight and 400 cubic feet of volume can be saved on submarines by substituting smaller and lighter fuel cells for the existing battery/diesel engine emergency power system. This would enhance performance in existing and future submarines b y making room for more electronic equipment, or permitting smaller, more maneuverable submarines. Submarines would also be quieter without the diesel engine. The program objectives are to produce a preliminary design for a 1500 kW Proton Exchange Membrane Fuel Cell system, floating on the grid and operating on ship's air and logistic diesel fuel. It will include preliminary design of components in the fuel ce ll stack to guarantee cell water balance, and preservation of membrane water content, therefore system longevity.
