Abstract
A fuel cell system includes a fuel cell stack and a storage tank in which at least part of generated water discharged from the fuel cell stack is stored in liquid form. The storage tank includes a first valve configured to adjust the pressure inside the storage tank to a pressure equal to or lower than a predetermined pressure that is higher than the pressure outside the storage tank.
Claims4
A fuel cell system comprising:
- a fuel cell stack;
- a storage tank in which at least part of generated water discharged from the fuel cell stack is stored in liquid form, wherein the storage tank includes a first valve configured to adjust a pressure inside the storage tank to a pressure equal to or lower than a predetermined pressure that is higher than a pressure outside the storage tank;
- and
- a second valve configured to introduce external air into the storage tank when the pressure inside the storage tank is lower than the pressure outside the storage tank.
