| 1. 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.
