Abstract
The air valve includes a supply valve configured to open and close an air supply passage through which the air gas to be supplied to the fuel cell stack from outside flows; a switching valve configured to switch between a state in which the air gas supplied from the outside flows through the air supply passage and a state in which the air gas supplied from the outside flows through a bypass passage that branches from the air supply passage; and a link mechanism connected to the supply valve and the switching valve and configured to actuate the supply valve and the switching valve. The link mechanism includes an arm portion fixed at the supply valve; and a cam plate fixed at the switching valve, wherein the cam plate includes a guide portion with which the arm portion is to contact.
