Dynamic modeling and control structure design of an experimental fuel processor

Abstract
In this work, a dynamic model is developed to describe an experimental
methane fuel processor which is intended to provide hydrogen for
a proton exchange membrane fuel cell (PEMFC) for power generation
(2-3 kWe). First-principle reactor models were constructed to describe
dynamic behavior for a series of reactions, starting from reforming
(SR/ATR), to high- and low-temperature water gas shift reactions
(HTS/LTS), and then to preferential oxidation (PROX) reactions. A
systematic procedure is proposed to identify dynamic-relevant model
parameters, and reasonable behavior description can be obtained.
Finally, two plantwide control structures, on-demand structure and
on-supply structure are designed and the performance of these two
control structures is evaluated for load disturbance rejection. The
results indicate that the on-demand control structure gives a rapid
transition to different power demands. (c) 2005 International Association
