摘要:
The invention relates to a method for producing a thin-film fuel cell. The inventive method comprises the following steps consisting in: depositing a first porous carbon electrode on a gas-diffusing substrate by means of plasma sputtering in a vacuum chamber, said electrode also including a catalyst which is used to accelerate at least one of the chemical reactions that take place in the fuel cell; depositing a membrane on the first electrode, said membrane being made from a proton conducting material and preferably having a thickness of less than 20 micrometers; and depositing a second porous carbon electrode on the membrane by means of plasma sputtering in a vacuum chamber, said second electrode also including a catalyst.

The present invention relates to a process for depositing a thin film of a metal alloy on a substrate, said film comprising at least four components and said alloy being either: an amorphous alloy containing at least 50 at% of the elements Ti and Zr, or a high-entropy alloy, the elements of which are chosen from the group consisting of Al, Co, Cr, Cu, Fe, Ni, Si, Mn, Mo, V, Zr and Ti; by simultaneous magnetron sputtering of at least two targets. The present invention also relates to a metal alloy in the form of a thin film comprising at least four components, which can be deposited on a substrate by implementing the process.

摘要:
The invention relates to a method for producing carbon electrodes (42), involving deposition on a support, in order to produce a fuel cell. The inventive method comprises steps consisting in alternately and/or simultaneously depositing porous carbon (40) and a catalyst (44) on the support (42), using a concentration gradient or in a homogeneous manner throughout the thickness thereof, by means of plasma sputtering in a vacuum chamber. The catalyst (44) is used to accelerate at least one of the chemical reactions that take place in the fuel cell and the thickness of each porous carbon layer is selected such that the catalyst deposited on said carbon layer is distributed throughout practically all of the layer, thereby creating a catalysed carbon layer. The total thickness of the catalysed carbon in the electrode is less than 2 micrometers and preferably at most equal to 1 micrometer.
