Abstract

A gas and liquid separator includes a first separating portion configured to separate a liquid droplet from a first exhaust gas discharged from a negative electrode of a fuel cell, a first container accommodating the first separating portion, a first storage reservoir storing water flowing down from the first separating portion, a second container provided at a lower side of the first storage reservoir, a second storage reservoir provided at a lower portion of the second container, and a valve apparatus including a valve discharging water stored in the first storage reservoir, wherein a second exhaust gas discharged from a positive electrode flows in the second container, and water discharged from the first storage reservoir is stored in the second storage reservoir.

Claims (19)

1. A gas and liquid separator comprising:

a first separating portion configured to separate a liquid droplet from a first exhaust gas discharged from a negative electrode of a fuel cell;

a first container accommodating the first separating portion in an internal space portion;

a first storage reservoir provided at a lower portion of the first container and storing water flowing down from the first separating portion;

a second container provided at a lower side of the first storage reservoir to be adjacent to the first storage reservoir, the second container including an internal space portion;

a second storage reservoir provided at a lower portion of the second container; and

a valve apparatus including a valve discharging the water stored in the first storage reservoir when the valve is open, wherein

a second exhaust gas discharged from a positive electrode of the fuel cell flows in the internal space portion of the second container,

the water discharged from the first storage reservoir is stored in the second storage reservoir, and

the valve apparatus includes a driving portion configured to open and close the valve apparatus, the driving portion being arranged between the first container and the second container, and the driving portion being arranged outside the first container and outside the second container.

2. The gas and liquid separator according to claim 1 , wherein the second container accommodates therein a second separating portion configured to separate water included in the second exhaust gas and allow the separated water to flow down to the second storage reservoir.

3. The gas and liquid separator according to claim 2 , wherein the second separating portion includes a collision plate configured to bend a flowing direction of the second exhaust gas flowing in the internal space portion of the second container.

4. The gas and liquid separator according to claim 1 , further comprising:

a drain pipe in which the water discharged from the first storage reservoir via the valve apparatus flows;

the drain pipe being exposed to the internal space portion of the second container; and

a drain port of the drain pipe being accommodated in an internal space portion of the second storage reservoir.

5. The gas and liquid separator according to claim 4 , wherein

the second container includes an introduction port of the second exhaust gas and a discharge port of the second exhaust gas, and

the drain port is arranged at a lower side than the introduction port and a lower side than the discharge port, when viewed along a flow direction of the second exhaust gas.
