摘　　要：提出一种新型的以Lewis酸作为电子传递体,构成Bronsted酸、Lewis酸共同作用于液流燃料电池系统,Lewis酸可以在热反应过程和电池反应过程改善电子传递过程,提升电池性能。对于PW12电池,Fe3+的加入可以将最大功率密度提高6.62倍,并且,混酸LCFC在处理纤维素时具有显著优势,可以将功率密度提升57%。A novel Bronsted acid and Lewis acid mixed catalyst LCFC with Bronsted acid worked as electron shuttlewas proposed. The performance of LCFC can be improved with the Lewis acid optimized electron transfer processesduring thermal reaction and cell reaction of LCFC. For LCFC with PW12, the output power density could be improved6.62 times with the addition of Fe3＋. Also, LCFC with mixed catalyst shows obvious advantages using cellulose asfuel with the improvement of output power density 57%.
