... ° C under humidified hydrogen ( 3 – 60 % H 2 O ) as fuel and air as oxidant. The anode active layer with finer and less porous microstructure increased the triple phase boundary length and improved cell performance under conditions that simulated higher fuel utilization. The material system...

... of fuel utilization and a precise control of gas composition, fuel, and airflow rates and temperature distribution. It seems quite difficult to maintain the same strict control of these parameters when the stack operates in an actual device. Therefore, it is of interest to investigate the effect...
