Abstract: A lift cart is used for car engine maintenance and comprises a moving base for mounting an oil pressure lifting device. One end of the oil pressure lifting device is provided with a platform having a rotatable adjusting device which is adjustable back and forth. The adjusting device is provided with a supporting plate, and a plurality of carrying structures for carrying different sized engine is positioned on the supporting plate. Such arrangements allow the maintenance man to make the height, back and forth, and rotation angle adjustment during disassembly of the engine.

Abstract: A protective coating is formed on a stainless interconnecting plate used in solid oxide fuel cell (SOFC). With the protective coating, a contact resistance of the plate is effectively lowered. Anode and cathode of SOFC are also prevented from being poisoned by chromium diffusion from the plate. Therefore, after a long time of use under a high temperature, a degradation rate for power generating of SOFC is reduced; and, thus, a working hour is prolonged. Hence, the SOFC can be mass-produced and large-scaled.
