    摘要： Disclosed is a process of preparing a catalyst supporting highly metal particles comprising, in the presence of ethylene and/or acetylene in a solution containing a metal-containing ion and a support on which metal particles produced by reduction of the metal-containing ion are supported, reducing by means of a reductant the metal-containing ion to the corresponding metal particles which are then supported on the support. According to the process of this invention, because of the presence of the ethylene and/or acetylene which is supposed to have a function of depressing the deposition of new metal particles present around the metal particles supported on the support, that is, the growth of the metal particles and another function of preventing the agglomeration among the metal particles supported, the catalyst of the desired properties can be prepared.

    摘要： Disclosed herein is a process of preparing a catalyst having narrow particle size distribution and supported with monodispersed metal particles of which a particle size is about less than 20 Å.
    In the present invention, propargyl alcohol is employed in place of a sulfur-containing agent for supporting the metal particles on a support thereby avoiding the contamination of the sulfur component and the high temperature treatment for decomposing the sulfur-containing agent. Accordingly, the resulting catalyst contains no sulfur contaminant and substantially no agglomerated metal particles.

    摘要： A solid polymer electrolyte fuel cell which contains a catalyst impregnated layer (7) in an ion exchange membrane (3) which is electrically isolated but ion conductive. In place of the catalyst layer, catalyst particles (29) existing in an anode and/or a cathode may be employed.
    The catalyst layer and the catalyst particles are attributable to the prevention of the lowering of a cell voltage and the employment of an inexpensive hydrocarbon ion exchange membrane and of a thin membrane.
