Method for recycling electrochemical proton exchange membrane (PEM) fuel cell, involves discharging platinum group metal (PGM) components contained in carrier of fuel cell during electrochemical reaction

摘要

The method involves supplying solvents over the external plates (9,10) of fuel cell (7). The PGM components contained in the carrier of fuel cell are discharged during electrochemical reaction. The discharged PGM components are delivered from fuel cell through electrode compartments (2,3) such that particles of discharged metal components are separated from the porous solvents such as alcohol or liquid.
