Fuel cell and method for making such a cell with large active surface and reduced volume

Method of this invention relates to a manufacturing fuel battery, which comprises an (9) is formed with multiple hole (10) and step at least two substrates, wherein the hole position of the single fuel cell unit, the hole is provided with a specific geometrical; for of the tapered or truncated a pyramid. Then each individual cell unit through electric connector network (11 and 12) power divider, and a reactant distribution network, supply modules the substrate (9), a battery and the basic modules (9 ') forming network. Finally, and at least two basic modules (9 '), the individual cell unit of the basic modules the individual the cell unit placing of the basic module.
