Embodiment Construction

[0038] Preferred embodiments of the present invention are described in detail below.

[0039] (1) "Autonomous start-up" of the fuel cell system according to the present invention means that the reformer and the fuel cell can be started without receiving electric energy or equivalent energy supply from the outside, whereby power generation can be started and supplied to an external load energy.

[0040] (2) "Hydrogen source" means a device for storing a raw material containing hydrogen and supplying the material as a raw material to the fuel cell system according to the present invention. More specifically, "hydrogen source" refers to a storage vessel for a hydrogen-containing feedstock or a supply pipe communicating with the storage vessel. The substance stored or supplied by the hydrogen source is ammonia, urea or a hydrocarbon gas such as methane.

[0041] (3) "Reformer" refers to a device that uses hydrogen-containing substances as raw materials to produce hydrogen. The ...

Abstract

A fuel battery system is provided which can start up without receiving an energy supply from outside. This fuel battery system 1 is provided with an input unit 11 which is connected to a hydrogen source 41, a reformer 12 which produces a hydrogen-containing gas, a hydrogen storage container 13, a fuel battery 15 which generates power using the hydrogen-containing gas, and a control unit 18. The control unit 18 stores a threshold value of the hydrogen-containing gas necessary for start-up of the fuel battery 15, and controls the amount stored in the hydrogen storage container 13 to be greater than or equal to the amount necessary for start-up of the fuel battery 15. Further, when starting up, the fuel battery 15 generates power by receiving a supply of the hydrogen-containing gas stored inthe hydrogen storage container 13 and supplies power to the reformer 12 from a first power supply path 16. The reformer 12 starts up and the necessary hydrogen is produced.

Description

technical field [0001] The present invention relates to fuel cell systems. In particular, the present invention relates to a fuel cell system including a hydrogen production device and a fuel cell that can start up and continue to operate without receiving an energy supply from the outside, such as during a power outage or natural disaster. Background technique [0002] Fuel cells are known to use hydrogen and oxygen as fuels and to generate energy through their chemical reactions. There are various fuel cells such as solid polymer fuel cells using ion exchange membranes as electrolytes, phosphoric acid fuel cells using phosphoric acid as electrolytes, and molten carbonate fuel cells using lithium or potassium carbonate as electrolytes. Among these fuel cells, solid polymer fuel cells are beginning to spread to households because they can operate at low temperatures of 100° C. or lower and can be miniaturized. [0003] Hydrogen used as fuel in fuel cells is more expensive ...
