摘要:
The present invention relates to a process for producing a fuel cell, comprising a step of forming a plurality of holes (10) in at least two substrates (9); each hole is in the seat of an individual fuel cell, the said holes having a particular geometry, such as a shape of a truncated cone or a truncated pyramid shape. The various individual cells are then electrically connected by networks of electrical connections (11, 12) and are supplied via a reactant distribution network, the assembly formed by a substrate (9), the cells and the networks constituting a base module (9′). Finally, at least two base modules (9′) are assembled, the individual cells of each base module being positioned facing the individual cells of the adjacent base module(s).

摘要:
The basic module has a large functional surface area compared with its relatively small global surface area.It is composed mainly of a multitude of micro-volumes (10, 110) installed in a closed space between a lower border (1), upper border (2) and side border (3). Each micro-volume wall is covered with a layer forming the membrane/electrodes basic element. Circulation of a first reactant to pass inside each micro-volume (10, 110) is enabled, whereas circulation of a second reactant to pass inside each micro-volume (10, 110) is enabled. The space between the micro-volumes (10, 110) may possibly be filled in with a porous material to stiffen the assembly.Applications for small sized fuel cells.
