TDA Research, Inc. (TDA) proposes a Novel Hydrogen Generation System (NHGS) to meet Navy requirements for reliable fuel cell generated power produced by low temperature fuel cells operating on high sulfur (1% sulfur, wt) logistic fuel. TDA's NHGS will steam reform logistics fuel into a gas stream which contains >90% H2 dry basis, less than 1 ppmv sulfur and less than 0.1 ppmv carbon monoxide (CO). TDA's NHGS operates with a very high efficiency. This effect is due to the design of the novel steam reformer, which is the key research item in Phase I. The novel steam reformer provides the endothermic heat of steam reforming and at the same time minimizes the quantity of steam required for steam reforming while operating at temperatures where stainless steel components can be used. All other components in the system have been used commercially. We anticipate that over 70% of the lower heating value of the logistics fuel can be consumed as hydrogen in the fuel cell to generate power, including the losses from 1) purging the fuel cell of non-reactive gases, 2) reforming the logistics fuel, 3) generating steam, and 4) the heat content of the exhaust products.
