摘要： The present invention relates to a method for producing a manifold for a fuel cell that is formed in a multilayer structure by injection-forming individual manifolds, each of which includes a coupling projection and a coupling guide, and by coupling the individual manifolds through a vibration coupling technique. In the present invention, the individual manifolds are disposed so that the coupling projections of the individual manifolds at the top are engaged with the coupling guides of the individual manifolds at the bottom engage with uniform gaps. Then, the individual manifolds at the bottom are pressurized upwardly, and the individual manifolds at the top are vibrated in a left and right direction at the same time, so that the individual manifolds at the top and at the bottom are coupled. It is characterized in that the individual manifolds at the top have non-horizontal projections whose length directions are not matched with the vibration direction of the individual manifolds, and the heights of the non-horizontal projections are variably formed.
