Provided is a method of recovering, from a fuel cell stack having a stack structure including a plurality of fuel cells stacked, materials forming the fuel cell stack, the fuel cells each including a membrane electrode assembly and two separators holding the membrane electrode assembly therebetween, the separators each being provided with a gas flow channel configured to supply a raw material gas to the membrane electrode assembly, the method including: a first step of supplying a solvent or a solvent and a reagent to the fuel cell stack through the gas flow channel, collecting the solvent which contains a material, and recovering the material from the collected solvent; and a second step of subjecting the fuel cell stack after the first step to a heat treatment to obtain a molten liquid or gas and recovering a material from the molten liquid or gas, the materials recovered including materials forming the membrane electrode assembly and the separators.",
