Patent ID: 7550220

Claim:
Miniature fuel cell basic module composed mainly of several micro-volumes ( 10 , 110 ), held fixed with respect to each other by a structure, and each comprising a stack of at least three layers forming an anode, an electrolyte and a cathode respectively, each micro-volume ( 10 , 110 ) having two parts uncovered by the three layers at the two ends; first means of circulation of a first reactant to pass inside each micro-volume; and second means of circulation of a second reactant outside the micro-volumes, wherein the structure is composed of two borders, the lower border ( 1 , 31 , 131 ) and the upper border ( 2 , 32 , 132 ) impermeable to the two reactants and between which the micro-volumes ( 10 , 110 ) are located, these two borders being drilled at the ends of the micro-volumes, thus forming part of the first means of circulation of the first reactant, wherein the second means of circulation of the second reactant are composed partly of a side border ( 3 , 103 ) impermeable to at least the second reactant, surrounding the assembly, and wherein the side border ( 3 ) is composed of a silicon ring.
