1. A manifold for a plurality of electrochemical fuel cells comprising:
a body defining a cavity therein;
a partition separating said cavity into a first group of a plurality of separate chambers and a second group of a plurality of separate chambers, wherein each of said chambers of each said group is in fluid communication with one of a fuel inlet, a fuel outlet, an oxidant inlet, and an oxidant outlet; and
a first interface and a second interface, wherein said interfaces each include:
a fuel interface section including a fuel inlet channel, and a fuel outlet channel; and
an oxidant interface section including an oxidant inlet channel, and an oxidant outlet channel, wherein said fuel interface section and said oxidant interface section each form a spiral;
wherein said fuel inlet channel and said fuel outlet channel of said first and second interfaces are respectively in fluid communication with said fuel inlet chamber and said fuel outlet chamber of said first and second groups of said chambers respectively, and
wherein said oxidant inlet channel and said oxidant outlet channel of said first and second interfaces are respectively in fluid communication with said oxidant inlet chamber and said oxidant outlet chamber of said first and second groups of said chambers respectively.
