Abstract
Disclosed is a method for recycling a hydrogen fuel cell of a new energy vehicle, including the following steps of: (1) discharging and disassembling a hydrogen fuel cell in turn to obtain a hydrogen supply system, an air supply system, a cooling system and a galvanic pile; (2) disassembling the galvanic pile into a catalyst and carbon cloth, and ashing to obtain ash; (3) adding an auxiliary agent into the ash, mixing, introducing inert gas, heating, introducing oxidizing gas, and absorbing tail gas by using an ammonium salt solution; and (4) adding a reducing agent into the ammonium salt solution absorbing the tail gas in step (3) to react, filtering, taking and cleaning a filter residue to obtain Pt.
