Abstract
A fuel cell control apparatus for controlling the supply amount of oxidizing gas to a fuel cell for producing electric energy by reaction between fuel gas and oxidizing gas includes a smoother for smoothing the output related quantity of the fuel cell, and an oxidizing gas feed determining device for determining the supply amount of the oxidizing gas on the basis of the output related quantity smoothed by the smoother, and therefore when controlling the amounts of the fuel gas and oxidizing gas depending on the output demand of the fuel cell, the substantial power generation efficiency is enhanced and the output is stabilized at the same time.
Claims1
A fuel cell control system comprising a fuel cell that produces electric energy generated by reaction between fuel gas and oxidizing gas and a reformer that generates a fuel gas to be supplied into the fuel cell by reforming reaction of reformate fuel, the system comprising:
- a reformate fuel detector configured to detect an amount of reformate fuel to be supplied into the reformer;
- an oxidizing gas feed determining device configured to determine a supply amount of the oxidizing gas to the fuel cell on the basis of the amount of reformate fuel to be supplied into the reformer;
- and
- an oxidizing gas feed adjuster configured to adjust the supply amount of the oxidizing gas on a basis of a reacting delay of the reforming reaction.
