Abstract
Official abstract text for this publication.
A fuel cell device is equipped with an ECU 60 which executes a start-up control of a fuel cell stack 20 , and executes a normal electric distribution control, after completion of the start-up control, for controlling a supply flow rate of a fuel gas to an anode electrode and a supply flow rate of an oxidant gas to a cathode electrode, so that a predetermined target current is supplied from the fuel cell stack 20 to an electric load 31 . The ECU 60 makes a current adjustment element 30 to be in a state where a current larger than a minimum current necessary for the fuel cell stack 20 in the normal electric distribution control is supplied from the fuel cell stack 20 to the electric load 31 , in the start-up control, during the period from starting of the supply of hydrogen to the anode electrode 22 until a gas channel of the anode electrode 22 is filled with hydrogen.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for controlling gas flow rates in a fuel cell device, the fuel cell device comprising a fuel cell stack configured from a plurality of membrane electrode assemblies, each of which is formed by arranging an anode electrode and a cathode electrode having a gas channel with an electrolyte membrane sandwiched in-between, an outlet of the anode electrode and an ejector provided in an anode inlet channel are connected by an anode outlet channel, so t…
