ABSTRACT:
The invention concerns a process for manufacturing electrodes for fuel cells operating at elevated temperatures, said process consisting in depositing by cathodic sputtering on a solid electrolyte substrate active mixtures of oxides and metals. The control of the relative rates of deposition of the various constituents of these active compositions is achieved by regulating individually independent magnetic fields acting on each of the components subjected to sputtering. A very high degree of homogeneity within the layers and of reproducibility of the compositions of the mixtures is achieved in this manner.
