Abstract

Official abstract text for this publication.

A recycling system in which anode off gas of a fuel cell is recycled to a stack includes a purge flow path purging the anode off gas passing through the stack, and a sprayer spraying pure gas supplied from a fuel tank to the stack. The sprayer is disposed on a path where the anode off gas passing through the stack is discharged, the purge flow path is spaced a certain distance from the sprayer, and the anode off gas passing through the stack is mixed with the pure gas by suction force of the sprayer to be introduced to the stack, thereby being recycled.

First claim

Opening claim text (preview).

What is claimed is: 1. A recycling system in which anode off gas of a fuel cell is recycled to a stack, comprising: a purge flow path purging the anode off gas passing through the stack; and an ejector spraying pure gas supplied from a fuel tank to the stack, wherein the ejector comprises a nozzle formed at an end of the ejector in a direction which extends toward the stack, and wherein the nozzle is disposed on a path where the anode off gas is discharged from the stack to the purge flow path, the purge flow path is spaced a certain distance from the ejector, and the anode off gas passing through the stack is mixed with the pure gas by suction force of the ejector to be introduced to the stack, thereby being recycled. 2. The recycling system of anode off gas according to claim 1 , wherein the purge flow path is disposed above a position where the pure gas is sprayed from the ejector. 3. The recycling system of anode off gas according to claim 1 , wherein the purge flow path is parallel to a supply line spraying the pure gas from the ejector to the stack. 4. The recycling system of anode off gas according to claim 1 , wherein the certain distance is 20 mm to 60 mm.
