Abstract

The invention provides a gas supply apparatus capable of suppressing (or reducing, etc.) damage due to reductions in temperature accompanying gas supply. A fuel cell system 10 comprises a hydrogen supply apparatus 15, having four hydrogen tanks 51, 52, 53, and 54, and a control unit 80 for controlling the supply of hydrogen gas from said tanks, where said control unit 80 not only detects the temperatures of the hydrogen tanks 51 to 54, but also limits the supply of hydrogen gas from a tank that serves as a supply source, based on the relationship between the temperature of the tank that has become the supply source and a guaranteed temperature range for guaranteeing the performance of said tank.

Description

[0001] This application is a divisional application of the application with the application number 200480021370.8 and the title of the invention "gas supply device" submitted on January 24, 2006. technical field [0002] The present invention relates to a gas supply device for supplying gas stored in a container to the outside. Background technique [0003] Conventionally, as a gas supply device that supplies gas stored in a container to the outside, a device that supplies hydrogen gas to a fuel cell using hydrogen as fuel is known. [0004] JP-A-2001-295996 and JP-A-8-115731 disclose a gas supply device for supplying hydrogen stored in a plurality of containers using a hydrogen storage alloy. [0005] Japanese Unexamined Patent Publication No. 2002-181295 discloses a gas supply device for supplying hydrogen in a container storing high-pressure hydrogen. [0006] When the gas stored in the container is supplied, the temperature of the container-related components such as re...
