A gas-liquid separator includes a housing, an inlet in the housing, a flow passage which is in communication with the inlet and through which a water-containing gas supplied through the inlet flows in a vertical direction, a gas-flow director configured to change a flow direction of the water-containing gas flowing through the flow passage from the vertical direction to the horizontal direction, and a gas-liquid separating portion configured to bring the water-containing gas, supplied from the gas-flow director into the housing, into contact with a plurality of separation blades in sequence to separate water from the water-containing gas.

Gas-liquid separator

A fuel cell system includes a fuel cell, a cathode off-gas discharge channel, a gas-liquid separator, and a cover member. The gas-liquid separator includes a body, a first discharge channel including a first valve seat at an end, and a first valve device including a first valve element and a first driver. The cover member covers at least the first discharge channel and the first valve seat in the gas-liquid separator, and includes a gas channel defining portion that defines a gas channel communicating with the cathode off-gas discharge channel between the cover member and the gas-liquid separator. The gas channel is configured such that a cathode off-gas flowing into the cover member comes into contact with the first discharge channel and the first valve seat and does not come into contact with the first driver.

Fuel cell system

A gas and water discharge unit for a fuel cell system that can be prevented from freezing even when it is formed using resin material. The unit includes a gas-liquid separator for separating produced water from fuel off-gas discharged from a fuel cell device, a gas and water discharge valve disposed downstream of the gas-liquid separator, and a resin unit body integrally formed with the gas-liquid separator and the gas and water discharge valve, in which the inside of the unit body includes a first channel with a valve seal at an end thereof on the gas and water discharge valve side, the first channel allowing communication between the gas-liquid separator and the gas and water discharge valve, a second channel communicating with the first channel via the gas and water discharge valve, and a heated water channel surrounding at least one of the first or second channel.
