Model-Based Control of an Integrated Fuel Cell and Fuel Processor With Exhaust Heat Recirculation

摘要: In this paper, we consider the dynamic and controlled operation of an integrated natural gas fuel processor system (FPS), a proton exchange membrane cell (PEM-FC), catalytic burner (CB). The FC provides power based on electrochemical reaction hydrogen. FPS generates hydrogen from through partial oxidation (CPOX) CB energy for preheating inlet flows by burning any excess exhaust. coupling these three systems poses challenging optimization control problem. Optimization is performed to generate air flow intake setpoints various load levels. optimal are used in static feedforward map that ensures maximum efficiency at steady state. Linear quadratic techniques then develop controller mitigate starvation regulate CPOX reactor temperatures. We show simulations designed observer-based feedback controller, which relies temperature measurements two reactors, speeds up transient response fourfold, as compared baseline when employed
