A valve and a fuel cell using the same are provided, the valve having a fluid inlet, a fluid outlet, a flow path communicating therebetween, a valve element provided in the flow path, a diaphragm which is disposed so as to separate the inside from the outside of the flow path and which is to be deformed by the difference in pressure between the inside and the outside of the flow path, a valve shaft connecting between the valve element and the diaphragm, and an actuator provided for the diaphragm. In the valve described above, the valve element is displaced by at least one movement of the diaphragm and the actuator to open and close the valve. Accordingly, the valve has a simple structure which can be easily miniaturized and which is unlikely to be degraded even when a corrosive fluid flows through the valve.
