Patent ID: 7432005

Claim:
A control system for controlling an output of a fuel cell, comprising: a fuel cell stack controller that receives an output request signal and that generates an oxidant request signal and a fuel request signal that is independent from the oxidant request signal using a first inverse model and the output request signal and without using an actual fuel cell power output, wherein the fuel cell stack controller stores the first inverse model; a fuel delivery controller that receives said fuel request signal, that generates a fuel command using a second inverse model and that generates a delivered fuel signal using a first model, wherein the fuel delivery controller stores the second inverse model and the first model; and an oxidant delivery controller that receives said oxidant request signal, that generates an oxidant command using a third inverse model and that generates a delivered oxidant signal using a second model, wherein the oxidant delivery controller stores the third inverse model and the second model, wherein said fuel cell stack controller receives said delivered oxidant signal from said second model and said delivered fuel signal from said first model and that calculates a power available signal using a third model, and the fuel cell stack controller stores the third model.
