PROBLEM TO BE SOLVED: To provide a manifold block for a fuel cell stack which eliminates the need of insulation coating and ensures excellent electric insulation properties for a coolant passage.SOLUTION: A manifold block for a fuel cell stack of this invention is coupled to a fuel cell stack module and has a gas passage and a coolant passage. The manifold block for the fuel cell stack includes a tubular insulation member which is inserted into the inner side of the coolant passage and is placed in close contact with an inner side surface of the coolant passage thereby electrically insulating the inner side surface of the coolant passage; and an insulation cover which is inserted into the inner side of the coolant passage and is placed in close contact with the insulation member thereby fixing and protecting the insulation member.
