Materials and Methods Objects of the investigation are carbon fiber and glass fiber reinforced laminates.
In order to reduce probability of higher materials inhomogeneity, all samples were fabricated with less thickness as required for mechanical testing.
Tensile, bending and interlaminar shear strength properties of the composite materials are slightly influenced by the void volume ratio.

Table 1 Analysis model size and properties of the SOFC stack materials.
In SOFC, the cell components deformations are different due to the CTE mismatches between the cell materials.
This might be affected by mismatch between electrode materials at the PEN structure of SOFC.

The metal alloys hydrides are the materials that have the ability to atomically bind the hydrogen and store them, whereas the chemical hydrides are materials that have hydrogen chemically bonded forming a complex and can release hydrogen by undergoing a chemical reaction.
