摘要: In this work, a gas diffusion layer (GDL) prepared with metallic ceramics TiC and TiN for a unitized regenerative fuel cell (URFC) was investigated. By the measurement of electrical conductivity, wettability and cycle voltammetry curves, the characteristics of the novel GDL and the conventional one were compared. A high corrosion-resistive and low-cost GDL with 80 wt. % TiC and 20 wt. % IrO2/TiN was expected to enhance the cycle performance of URFC. And the loading of IrO2 was only 0.6 mg/cm2. The URFC with the novel GDL exhibited the similar initial performance under both electrolysis and fuel cell modes as that using the conventional GDL. Moreover, the life cycle testing over 60 hours showed that the URFC with the novel GDL was more stable than the URFC with the traditional GDL, indicating the GDL with TiC and TiN was beneficial to improve the cycle life of the URFC.
