A composite material, which may be further applied as a single layer fuel cell, was synthesized using solid state synthesis method. Composite consisted of two components. The first was a nanoceramic proton conductor – calcium doped lanthanum niobate. The second one was a nanoceramic semiconductor oxide composed of lithium, nickel and zinc oxides respectively. Structural and electrical investigations were performed on the received material. Scanning electron microscope images showed that the microstructure on the surface of this material is homogeneous. Energy dispersive X-Ray diffraction confirms that the components of the investigated composite are mixed together in a volume of material allowing to current flow through the percolation threshold. Open circuit voltage was changing during measurement from 0.8V to 0.6V. Moreover, the material did not change its structural properties during the current flow, hence it could be a good candidate to the production of single layer fuel cells.
