摘要： A solid polymer fuel cell which can stably generate electric power for long, because the cell is enabled to uniformly supply a fuel gas to all anodes by means of extended flow passages which are extended from anode-side flow passages and formed on a anode-side plate on the downstream side of the ends of the anodes in the direction of fuel gas flow, a water absorbing means for nearly uniformly performing water absorption, water retention, and drainage on all channels provided at the ends of the extended flow passages, and a selective gas discharging means for discharging a gas more selectively than water on the upstream side of the water absorbing means. In addition, the power generation characteristics and service life of the fuel cell can be improved further, because the cell can maintain a solid polymer film in a moist state as a whole and can efficiently supply the fuel gas to all anodes by a means for distributing the fuel gas to the inlet sections of the anode-side flow passages and a means for distributing water from a water source to the inlet sections of the anode-side flow passages through holes having a prescribed form and leading to the inlet sections of the anode-side flow passages.

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.
