Abstract
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 () installed in a closed space between a lower border (), upper border () and side border (). 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 () is enabled, whereas circulation of a second reactant to pass inside each micro-volume () is enabled. The space between the micro-volumes () may possibly be filled in with a porous material to stiffen the assembly. Applications for small sized fuel cells.
