Abstract
A fuel cell (100) includes an end plate cover (200) to which a sound-absorbing member (210) is attached and an injector block (180) in an end plate (170F) on one end side of a cell stack (102S). The sound-absorbing member (210) is attached to a sound-absorbing seating surface (203) forming a gas introduction path (202) of the end plate cover (200) which merges a gas jetted from injectors (180a to 180c) to guide it to a fuel gas supply path in a cell coupling portion (170Fc), and is fixed to a convex column (205) in a state in which the convex column (205) is inserted to a through hole (211).
Claims8
A fuel cell comprising:
- a cell stack configured to have a stack structure including a plurality of cells as power generation units being stacked in layers;
- an end plate attached to one end of the cell stack;
- an injector attached to one side of the end plate and configured to jet a fuel gas;
- a path provided in an other side of the end plate so as to guide the fuel gas jetted from the injector to the cell stack;
- and
- a sound-absorbing member attached to a portion of a plate surface on the other side of the end plate which corresponds to the path.
