A Review of Pd Based Multimetallic Anode Electrocatalysts for Direct Formic Acid Fuel Cells

Abstract

Due to the increasing population and developing industry, the energy demand in the world is increasing. Fuel cells are technologies that can meet this need without a negative impact on the environment. However, for the commercialization of fuel cells, their costs must be reduced and their efficiency increased. An important way to reduce cost is to reduce the amount of Pd, a precious metal used as an anode catalyst, by adding a second metal. The aim of this study is to explain how Pd increases the activity when used as an anode catalyst with a second metal for the formic acid electrooxidation.
