Abstract

A fuel gas injection apparatus includes a chamber, a heat exchanger, a supply manifold, injectors, and a mount body. The chamber is in communication with a fuel gas tank, and the heat exchanger is in communication with the chamber. The supply manifold is in communication with the heat exchanger and has a plurality of branched flow channels for flowing a fuel gas. The plurality of injectors detachably communicate with the branched flow channels of the supply manifold. The mount body is in communication with the plurality of injectors and guides the fuel gas injected from plurality of injectors to a fuel cell stack. The chamber and the heat exchanger are attached to the mount body.

First claim

What is claimed is:

1. A fuel gas injection apparatus comprising:
a chamber in communication with a fuel gas tank in which a fuel gas is stored;
a heat exchanger that is in communication with the chamber and that is configured to exchange heat with the fuel gas;
a supply manifold that is in communication with the heat exchanger and that has a plurality of branched flow channels for flowing the fuel gas;
an injector that detachably communicates with the branched flow channels of the supply manifold; and
a mount body that is in communication with the injector and that is configured to guide the fuel gas injected from the injector to a fuel cell,
wherein the chamber and the heat exchanger are attached to the mount body.

2. The fuel gas injection apparatus according to claim 1 , comprising an intermediate joint that is provided between the heat exchanger and the supply manifold and that is configured to bring the heat exchanger and the supply manifold in communication with each other.

3. The fuel gas injection apparatus according to claim 2 , comprising a pressure sensor that is provided at a position close and along the intermediate joint and that is configured to detect a pressure of the fuel gas flowing through the intermediate joint.
