1. A manifold for supplying gas to an electrochemical cell, the electrochemical cell including first and second gas channels extending from a base end portion to a leading end portion of the electrochemical cell and communicating with each other at the leading end portion, the manifold comprising:
a first manifold main body including a first gas chamber, the first gas chamber being configured to communicate with the first gas channel, the first manifold main body including a first top plate, a first bottom plate and a first side plate, the first top plate including a first through hole for permitting communication between the first gas channel and the first gas chamber; and
a second manifold main body including a second gas chamber, the second gas chamber being configured to communicate with the second gas channel, the second manifold main body being disposed in the first manifold main body, the second manifold main body including a second top plate, a second bottom plate and a second side plate, the second top plate including a second through hole for permitting communication between the second gas channel and the second gas chamber, the first bottom plate of the first manifold main body and the second bottom plate of the second manifold main body being spaced from one another and being disposed in facing relation with one another.
