The invention discloses a waste fuel battery recycling method. The method comprises the following steps: a, disassembling a waste fuel battery, separating a bipolar plate and a membrane electrode, and performing crushing treatment on the membrane electrode; b, removing organic impurities on the surface of the bipolar plate; c, performing pyrolysis treatment on the crushed membrane electrode, and cleaning membrane electrode residue after the pyrolysis; and d, drying the membrane electrode residue, leaching platinum in the membrane electrode residue with a hydrochloride and oxydol mixed solution, and reacting the platinum-containing solution and ammonia water to obtain a chloroplatinic acid precursor. According to the method, the valuable component of waste fuel battery is recycled, thereby avoiding resource waste and achieving great economic value; in the process of recovering platinum in the waste fuel battery, no aqua regia, concentrated nitric acid or other strongly acid solutions are needed, so that no operation risk exists,, no adverse influence is made to the operating environment, and the treatment solution does not need to be subjected to post treatment; and the process is simpler in comparison with the traditional treatment method, avoids secondary pollutant caused by post treatment, realizes energy saving and environment friendliness, and is suitable for industrial batch treatment.
