FUEL SUPPLY DEVICE IN FUEL CELL

摘要

PURPOSE: Provided is a fuel supply device in fuel cell, which is suitable to allow the fuel cell to generate an electricity without separate reforming unit, by using a hydrogen occurred in Ni-MH based secondary cell as a fuel of fuel cell. CONSTITUTION: The device comprises a stack(10) which comprises a cathode and an anode, in which hydrogen gas supplied to the anode is electrochemically reacted with air supplied to the cathode to form an electromotive force; and a secondary cell(11) for starting of the stack. The secondary cell is a secondary cell based on Li-MH(which is a metallic alloy for hydrogen storage), in which the cathode stores a hydrogen when charged, and discharges a hydrogen when discharged. The secondary cell has means(13) for hydrogen extraction and supply, which is to extract a hydrogen discharged from the secondary cell and supply the hydrogen as raw material of the stack(10).
