Fuel cell system including an ammonia remover and method of operating the same

摘要

A fuel cell system 100 includes: a reformer 1 configured to generate a hydrogen-containing gas by using a raw material; a fuel cell 6 configured to generate electric power by using the hydrogen-containing gas; an ammonia remover 5 configured to remove ammonia from the hydrogen-containing gas generated in the reformer before the hydrogen-containing gas is supplied to the fuel cell; a fluid passage configured to allow the ammonia remover to be in communication with the atmosphere; an on-off valve 8 provided on the fluid passage and configured to allow and block the communication between the ammonia remover and the atmosphere; and a controller 80 configured to open the on-off valve in at least one of a water draining process and a water loading process of the ammonia remover.

1. A fuel cell system comprising:
a reformer that generates a hydrogen-containing gas by using a raw material; a fuel cell that generates electric power by using the hydrogen-containing gas; an ammonia remover that removes ammonia from the hydrogen-containing gas generated in the reformer before the hydrogen-containing gas is supplied to the fuel cell; a fluid passage that allows space in an upper part of the ammonia remover to be in communication with an atmosphere; an on-off valve that is provided on the fluid passage and allows and blocks the communication between the space in the upper part of the ammonia remover and the atmosphere; and a controller including a processor and a memory storing a program, wherein the program, when executed by the processor, causes the controller to perform operations including: opening the on-off valve in at least one of a water draining process and a water loading process of the ammonia remover.
