燃料電池の膜電極集合体から貴金属を浸出させるための簡易化方法
Document Type and Number:
Japanese Patent JP5784307
Kind Code:
B2
Abstract:
The membrane electrode assemblies of fuel cells are recycled to recover the catalyst precious metals from the assemblies. The assemblies are cryogenically embrittled and pulverized to form a powder. The pulverized assemblies are then mixed with a surfactant to form a paste which is contacted with an acid solution to leach precious metals from the pulverized membranes.
