Anode catalyst for fuel cell membrane electrode and preparation method thereof

The invention discloses an anode catalyst for a fuel cell membrane electrode and a preparation method of the anode catalyst. The anode catalyst comprises a Pt/carbon catalyst, an ionomer and an anti-reversion catalyst, and the preparation method comprises the following steps: directly adding the anti-reversion catalyst into the Pt/carbon catalyst, and controlling the thickness of a catalyst layer by adjusting the proportion of each component in the catalyst, so as to prepare the anti-reversion and high-durability fuel cell membrane electrode. The reversible catalyst is an iridium or ruthenium elementary substance, an iridium or ruthenium oxide, or a composite catalyst of the iridium or ruthenium elementary substance or the iridium or ruthenium oxide. And the thickness of the catalyst layer is 1-8 microns. According to some thickness examples of the membrane electrode, ultrahigh anti-reversion durability can be obtained, the preparation method is simple, different design requirements can be met, and the use am
