In recent years, solid oxide fuel cells fueled with ammonia have been attracting intensive attention. this work, was supplied to the Ni/yttria-stabilized zirconia (YSZ) cermet anode at 600 and 700 °C, change of electrochemical performance microstructure under open-circuit state studied in detail. The influence exposure on Ni also investigated by using Ni/YSZ powder film deposited a YSZ disk. obtained results demonstrated that partially nitrided an atmosphere, which considerably roughened surface. Moreover, destruction support layer confirmed for anode-supported cell upon temperature cycling test between °C because nitriding phenomenon Ni, resulting severe degradation.
