Abstract:

Formic acid is a promising material for chemical hydrogen storage,which can be used as direct fuel for cryogenic liquid fuel cell.As anode materials for direct formic acid fuel cell（DFAFC）,Pd-based catalysts have good catalytic activity for formic acid oxidation,which can overcome the poisoning of CO and carry out via direct route of the electrochemical oxida-tion of formic acid.Reducing noble metal content,improving catalytic activity and stability are the main directions in the re-search field of Pd-based catalytic materials.The electrooxidation and catalytic mechanism of Pd-based catalyst for formic acid at present was mainly introduced.The preparation of Pd alloy catalyst,the control of special morphology and the enhancement of carbon loading on formic acid oxidation activity in recent five years were reviewed.It has practical significance for the continuous development of Pd-based catalyst.

Key words: formic acid, fuel cell, palladium catalyst, carbon loading
