A solid polymer electrolyte membrane and a catalytic layer are properly assembled even when the solid polymer electrolyte membrane and an ion exchange resin in the catalytic layer are formed of different materials. In a fuel cell, a solid polymer electrolyte membraneis provided with a first solid polymer electrolyte membrane, and second solid polymer electrolyte membranesandprovided at respective sides thereof. The second solid polymer electrolyte membranesandare formed of the same material as the ion exchange resin (not shown) included in a catalytic layerand a catalytic layer

Solid polymer electrolyte membrane, solid polymer electrolyte fuel cell using the membrane and method of fabricating the same

An electrode for a rechargeable lithium battery which includes a current collector and a thin film composed of active material that stores and releases lithium and deposited on the current collector, the electrode being characterized in that the current collector has irregularities on its surface and the thin film has spaces extending in a thickness direction of the thin film and configured to increase their width dimensions toward valleys of the irregularities on the current collector surface.
