5 ESSENTIAL ELEMENTS FOR DIFFUSION BONDED CRYSTAL

The fracture conduct and fracture mode on the diffusion-bonded joints had been elucidated by macro fracture and magnified floor morphologies. The macro fracture morphologies (flat fracture) exhibit that the propagation of crack happened alongside the MEA/DD5 interface in tensile tests on the joints obtained at 1020, 1050, and 1080 °C (Figure 8a–
