Abstract:
A coolant flow field is formed between first and second metal separator plates of a joint separator (fuel cell separator). First and second beads protrude from the first and second metal separator plates. The beads include inner beads for preventing leakage of a reactant gas. An air release passage and a coolant drain passage extend through the fuel cell separator in a separator thickness direction, and the air release passage and the coolant drain passage are connected to a coolant flow field through a first connection channel and a second connection channel formed by recesses on the back of protrusions of the first and second beads.

Claim (Index 1):
A fuel cell separator including two metal separator plates joined together, a bead protruding from one surface of each of the metal separator plates where a reactant gas flows, a reactant gas flow field being formed on the one surface of the metal separator plate and configured to allow a reactant gas of a fuel gas or an oxygen-containing gas to flow along the reactant gas flow field, a coolant flow field being formed between the two metal separator plates, a reactant gas passage connected to the reactant gas flow field extending through the fuel cell separator in a separator thickness direction, the bead including a seal bead configured to prevent leakage of the reactant gas,\n wherein at least one of an air release passage and a coolant drain passage extends through the fuel cell separator in the separator thickness direction, and at least one of the air release passage and the coolant drain passage is connected to the coolant flow field through a connection channel formed by a recess on back of a protrusion of the bead.
