A fuel cell comprised of a proton conductive electrolyte film sandwiched between a pair of catalyst layers, wherein the catalyst layer of at least the cathode is comprised of a mixture including a catalyst ingredient, an electrolytic material, and a carbon material, the carbon material is comprised of a catalyst-carrying carbon material carrying the catalyst ingredient and a gas-diffusing carbon material not carrying the catalyst ingredient, and the catalyst-carrying carbon material has an amount of adsorption of water vapor at 25&#xb0; C. and a relative humidity of 90% of 50 ml/g or more.

Fuel cell and fuel cell use gas diffusion electrode

The present invention provides a resin-coated stainless steel foil capable of maintaining a strong adherence force to the film even in an electrolytic solution to exhibit good corrosion resistance and excellent in the workability, design property and piecing resistance, and a container and a secondary battery each using the resin-coated stainless steel foil. A resin-coated stainless steel foil having a chromate treatment layer of 2 to 200 nm in thickness on at least one surface of a stainless steel foil and having at least a polyolefin-based resin (A) layer containing a functional group having polarity on the chromate treatment layer; and a container and a secondary battery each using the resin-coated stainless steel foil are also provided.

A composite coated metal sheet comprising a coated film having a low environmental impact prepared free from hexavalent chromium, and having good corrosion resistance equivalent to that provided by chromate treatment and excellent adhesiveness between the coated film and a resin layer formed on the coated film. Also, a treatment agent and a method of manufacturing the composite coated metal sheet with the treatment agent is described. The composite coated metal sheet comprises a coated film formed on a surface of a plated metal sheet or metal sheet, the coated film contains an oxide and/or a hydroxide of metal other than chromium, and an organic component comprising modified and/or unmodified functional group(s).
