Abstract: A stainless steel sheet useful as a separator for a low-temperature fuel cell has the surface state that a lot of fine projections (p) stand close together around many fine pits (d) formed over a whole surface. The surface state is realized by alternating electrolytic etching in a ferric chloride solution. When the stainless steel separator is built in a fuel cell, contact resistance between the separator and a graphite electrode is kept at a lower level even in a corrosive atmosphere. Consequently, the fuel cell can be driven with high power-generating efficiency over a long term even under severely corrosive conditions without generation of massive Joule heat.

Abstract: A stainless steel separator, which is good of corrosion-resistance and low of contact-resistance, is proposed for a fuel cell. Its surface faced to a fuel electrode is pickled, which the other surface faced to an oxidizing electrode is roughened by electrolytic etching or the like. The roughening treatment may be performed before or after pickling and passivation. The roughened surface of the stainless steel separator without pickling or passivation may be faced to the oxidizing electrode.

Abstract: An iron-based heat-generating material excellent in oxidation resistance at an elevated temperature which comprises an iron-based alloy capable of generating heat by passing electricity therethrough and a coating of aluminum and oxygen formed on the surface of the alloy, the amount of the oxygen in the coating is less than the stoichiometric amount of oxygen in Al.sub.2 O.sub.3. The material can be prepared by vacuum evaporation of Al onto the surface of the iron-based alloy wherein an oxygen partial pressure in a vacuum gaseous atmosphere for the vacuum evaporation is adjusted so that there is formed on the surface of the alloy a coating consisting of aluminum and oxygen, the amount of the oxygen in the coating being less than the stoichiometric amount of oxygen in Al.sub.2 O.sub.3. When the material is heated in ambient or oxidizing atmosphere, an outermost layer of the coating is rapidly converted to Al.sub.2 O.sub.3.

Abstract: An intermetallic compound such as Nb.sub.3 Al exhibits the phenomenon of self-disintegration, when hydrogen is adsorbed in the intermetallic compound. This self-disintegration is used for the pulverization of the intermetallic compound material. The material is autogeneously pulverized into very fine particles only by adjusting an atmosphere to which the material is exposed, since the pulverizing reaction occurs between hydrogen existent in the atmosphere and the active surface of the intermetallic compound. The pulverized intermetallic compound having irregular shapes and large specific surface area is useful in various technical fields, e.g. as a superconductive material, a heat-resistant material, a magnetic body or a hydrogen-absorbing material.
