Abstract
The ethanol steam reforming (ESR) is a promising alternative energy production technique from renewable resources for Solid Oxide Fuel Cell (SOFC). Herein, the bimetallic supported NiMo/CZY catalyst demonstrates high catalytic activity and stability toward ethanol steam reforming (ESR) reaction and excellent coking resistance than mono-metallic Ni catalyst without Mo. The catalytic activity of synthesized Ni/CZY with and without Mo was conducted at 800-400 oC and an S/C ratio of 2, with a weight-hourly-space-velocity (WHSV) of 156 h-1. The XRD analysis illustrates that the bimetallic NiMo/CZY catalyst has high resistance to coking and sintering compared to mono-metallic Ni/CZY catalyst. The H2-TPR showed that NiMo/CZY has a lower reduction temperature than Ni/CZY due to NiMo and CZY support's high interaction. This catalytic enhancement can be associated with the high dispersion of NiMo nanoparticles over CZY support material and the high oxygen storage capacity of CZY support material. This unique material, NiMo/CZY catalyst, was introduced as a micro-reforming active layer on the Ni-YSZ anode supported single SOFC cells. The SOFC cells with a coated layer of and infiltrated NiMo/CZY illustrated high electrochemical performance and stability with a low degradation rate for ~ 100 hours.
