Abstract.
As the porous anode-supported cells have been studied for an intermediate temperature SOFC (500∼800 o C), high performance of anode materials is required.
The porosities of the porous materials were calculated using the Archimedes method.
We examined the fractured surface on two materials, NiO-8mol%YSZ and NiO-10mol% YSZ, by SEM as shown in Fig. 5.

With this emerging technology, it is possible for the first
time to rapidly deposit thin or very thick layers (mm to cm+) of a wide range of metals, and even some
composite materials, without melting or vaporization, at or near room temperature, in an ambient air
environment.
Introduction Cold spray [1-7] is a new coating method for the deposition of metal, alloy, polymer, or composite powder material onto various substrates.
The cold spray process was developed in the mid-1980s at the Institute for Theoretical and Applied mechanics of the Russian Academy of Science in Novosibirsk.
As shown in the figure, the distinguishing feature of the cold spray is the ability to produce coatings with the jet temperature range between 0 and 700͠, which is always lower than the melting point for the candidate powder and substrate materials.
