Temperature dependencies of methaneconversion (1%CH 4 in air, 1000h -1 ) ondifferent catalysts deposited on metal foil.It was concluded that the technology developed has no limitation in scaling and thereforeit can be widely applied in future for the preparation of catalysts on metal surfaces. Inparticular, this technique is planned to be applied for deposition of catalytic coatings on theintegrated metal separator for methane reforming in high temperature fuel cells.Fig. 3.
