A dynamic model is presented that predicts the transient characteristics of an integrated autothermal fuel reformer and gas turbine engine for extracting a high purity stream of hydrogen from logistical fuels such as F76 marine diesel or JP-5 for use in a shipboard proton exchange membrane (PEM) fuel cell power plant. The model incorporates a water-gas shift reactor for increasing hydrogen yield, and a separation membrane for extracting a pure stream of hydrogen gas from the reformer output. Compressed air supply and energy recovery is achieved by an integrated gas turbine generator. The dynamic model serves as a testing ground for the development of control methodologies and to predict limitations in transient response during electrical load variations.
