NOVELTY - Fuel cell comprises anode catalyst, which is made up of molybdenum based agent (main active component), active auxiliary agent and carbon based agent (carrier). The weight ratio of main active component and active auxiliary agent is 80:20-95:5 and the weight ratio of main active component and carrier is 20:80-80:20.    USE - Fuel cell used in vehicle (claimed).    ADVANTAGE - The fuel cell generates greater electric potential and electric current, and has improved durability.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing fuel cell anode catalyst, which involves:    (A) mixing pre-treated carrier with deionized water for 30 minutes in a reactor by using ultrasonic wave generator to obtain mixture;    (B) adding aqueous solution of active-component precursor (10 mg per ml), carrier and aqueous solution of formic acid to the obtained mixture;    (C) treating the components of the reactor ultrasonically for 30 min to obtain mixture;    (D) placing the obtained mixture in hood for 24-120 hours to obtain a mixture;    (E) filtering the obtained mixture to obtain a product;    (F) washing the obtained product using deionized water to remove all chlorine ions to obtain product;    (G) drying the obtained product at 80 degrees C for 5-15 hours by using vacuum oven to obtain main active component;    (H) boiling precursor of auxiliary agent in deionized water to which aqueous solution of sodium bicarbonate is added to obtain mixture;    (I) boiling the mixture for 20 minutes to obtain a reaction mixture;    (J) cooling the obtained reaction mixture and filtering to obtain product;    (K) washing the obtained product with deionized water to remove all chlorine ions to obtain product;    (L) drying the obtained product at 80-105 degrees C to obtain constant weight product;    (M) drying the constant weighing product at 350-800 degrees C for 2 hours in the presence of nitrogen to obtain active auxiliary agent; and    (N) combining the main active component and active auxiliary agent to obtain fuel cell anode catalyst.
