Integrated fuel processor and fuel cell system control method

摘要

The present invention provides a novel method of controlling a mobile, integrated fuel processor and fuel cell system that utilizes an innovative combination of feedback and feed forward control loops maintain the reformer temperature and hydrogen permeate pressure in the system with the operating parameters of the fuel reformer being adjusted to achieve rapid and more reliable load following when transient conditions occur.

主权项

1. An integrated fuel processor and fuel cell system comprising:
a controllable fuel supply; a fuel processor connected to said controllable fuel supply and operatively configured to receive fuel from said controllable fuel supply and convert a portion of said fuel into permeate; a fuel cell connected to said fuel processor and operatively configured to receive permeate from said fuel processor; a power management module connected to an output of said fuel cell; an energy storage device connected to an output of said power management module; an electrical load connected to another output of said power management module; and a fuel processor electronic control unit, said electronic control unit operatively configured to control the rate at which fuel is supplied to said fuel processor as a function of a temperature within said fuel processor and a pressure of said permeate.
