摘要： A cell unit for use in fuel cells of the type using an electrode portion having an anode formed of a plate or film on one surface of an electrolyte and a cathode formed of a plate or film on the other surface. An anode side plate of the invention has stepped portions to form recesses which accommodate the electrode and provide an anode side chamber facing the anode. A cathode side plate having a cathode side chamber facing the cathode is also accommodated in the recessed portions of the anode side plate. A fuel supply manifold and a fuel discharge manifold can extend through the stepped portions. Use of such cell units reduces the number of seal members required between fuel or oxidant manifolds when cell units are stacked to form a fuel cell stack. Such reduction in seal members simplifies fabrication of the units and renders the cell unit easier to maintain and repair.
