Abstract
Official abstract text for this publication.
To suppress increase of a pressure loss in a channel and blocking of the channel due to water adhering to a rectification mesh provided downstream of a butterfly valve. A fuel cell system includes: a butterfly valve provided on a pipe between a fuel cell and another component; and a rectification mesh provided on a downstream side of gas flowing in the pipe relative to the butterfly valve, a mesh that rectifies a flow of the gas being formed in the rectification mesh. The rectification mesh has, in its lower end part in a vertical direction, a first opening part in which the mesh is not formed.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel cell system comprising: a butterfly valve provided on a pipe between a fuel cell and another component; and a rectification mesh provided on a downstream side of the butterfly valve along a direction of flow of gas flowing in the pipe, the rectification mesh having a mesh that rectifies a flow of the gas, wherein the rectification mesh has a first opening part in a lower end part of the rectification mesh in a vertical direction, wherein the mesh is not formed in the first opening part. 2. The fuel cell system in accordance with claim 1 , wherein in a center part of the rectification mesh, the rectification mesh further has a second opening part in which the mesh is not formed, the second opening part extending in an axial direction of rotation of a valve body of the butterfly valve. 3. The fuel cell system in accordance with claim 2 , wherein the second opening part is formed so as to enclose a region obtained by projecting the butterfly valve at a predetermined maximum degree of opening on the rectification mesh along the direction of the flow of the gas. 4. The fuel cell system in accordance with claim 1 , wherein the butterfly valve is disposed in an orientation such that a valve body rotates with a horizontal direction.
