    摘要： A fuel cell including a unit cell and a separator panel alternatingly stacked on one another. The unit cell includes an electrolyte membrane sandwiched between a fuel electrode and an oxidant electrode. The separator panel includes parallel fuel flow paths extending from a fluid supply port to a fluid discharge port for supplying fluid fuel to the fuel electrode and parallel oxidant flow paths extending from a fluid supply port to a fluid discharge port for supplying oxidant fluid to the oxidant electrode. At least the oxidant flow paths include groups of parallel flow paths, which extend back and forth within divided regions of the main surface of the separator panel. The oxidant flow paths may include groups of parallel flow paths, positions along the groups of the parallel flow paths at equal distance from the respective fluid supply port being distributed substantially evenly over the main surface of the separator panel. Also, groups of parallel flow paths extend back and forth within a region defined by a projection of the divided regions through which the oxidant flow paths extend. The ridge width of ridges defined between grooves within the parallel flow path group is smaller than the ridge width of the ridges defined between the grooves of the parallel flow path group adjacent to each other.

    摘要： A lithium ion secondary battery. The battery maintains an electrical connection between electrodes without using a firm case and can have an increased energy density at a reduced thickness while exhibiting excellent charge and discharge characteristics. The battery includes a plurality of electrode laminates each having a positive electrode, a negative electrode and a separator. The positive electrode includes a positive electrode active material layer and a positive electrode current collector. The negative electrode includes a negative electrode active material layer and a negative electrode current collector. This separator is impregnated with a lithium ion-containing electrolytic solution and is interposed between the electrodes in intimate contact. The positive electrode, negative electrode and separator are joined together in intimate contact with porous adhesive resin layers having through holes. The through holes are filled with electrolytic solution to connect the positive electrode active material layer, the negative electrode active material layer and the separator layer.
