NOVELTY - The apparatus (10) has a fine particle moving mechanism (21) and an alloy particle supply mechanism (26) that convey the fine particles (28) and the alloy particles (25) respectively in predetermined manner. The shortest distance"d"between the alloy particle supply mechanism and the fine particle moving mechanism, the width"W"for which the fine particles are conveyed and the width"w"for which the alloy particles are conveyed are set to satisfy predetermined relationship.    USE - Fine particle support apparatus for use in manufacture of electrode for methanol polymer electrolyte fuel cell used in power supply of mobile device.    ADVANTAGE - The fine particle support apparatus allows manufacture of the high quality fine particle support for the electrode of the fuel cell at low cost without causing any malfunctioning, so that fuel cell with very high output voltage efficiency can be manufactured easily. The time dependent characteristic degradation of the electrode of the fuel cell can be prevented. The suitable support for fuel cell electrode be obtained by proper selection of the fine particles and inert gas.    DETAILED DESCRIPTION - The apparatus has the fine particle moving mechanism for conveying the fine particles at predetermined speed and the alloy particle supply mechanism supplies alloy particles of size smaller than that of the fine particles. The quantity"X"(atom/secondasteriskcm2) of the alloy particles to be supplied per unit time and unit area by the alloy particle supply mechanism and the time"T"required for the fine particle to pass through the alloy particle supply region are set such that the Xx T lies between 1x 1016-1x 1019. A limiting unit (22) limits the flow volume of the fine particles along the conveyance direction, in predetermined manner such that the thickness of the fine particle layer formed by the fine particle moving mechanism is 0.06-2mm. The shortest distance"d"in cm, between the alloy particle supply mechanism and the fine particle moving mechanism, the width"W"in cm, for which the fine particles are conveyed and the width"w"in cm for which the alloy particles are conveyed are set in predetermined manner such the W-w lies between 0.4x d and 7.4x d. A fine particle circulation mechanism (34) circulates the fine particles that are collected by a fine particle collection mechanism (27) to fine particle supply structure (24). An INDEPENDENT CLAIM is also included for fine particle support method for manufacture of electrode for fuel cell which involves controlling operation of the fine particle moving mechanism and the alloy particle supply mechanism in predetermined manner by using decompression devices.
