摘要： It is an object of the present invention to provide a method of producing a membrane electrode assembly using an interface resistance reducing composition which can simply reduce the resistance of the interface between an electrode and an electrolyte membrane in a short time at low temperatures at low pressure without polimerization while maintaining an effect of suppressing a fuel crossover even with an electrolyte membrane having high heat resistance, high strength, a high tensile elastic modulus and a low water content. This is achieved by a method of producing a membrane electrode assembly formed by sandwiching an electrolyte membrane between a pair of electrodes, comprising the steps of bonding at least one electrode to the electrolyte membrane sandwiching an interface resistance reducing composition containing a plasticizer between the electrode and the electrolyte membrane, and a membrane electrode assembly formed by sandwiching an electrolyte membrane between a pair of electrodes, wherein the membrane electrode assembly has a layer (A) at least between one electrode and the electrolyte membrane, and the value of the storage modulus C is 1 GPA or more when the storage moduli of the electrolyte membrane and the layer (A), which are measured with an ultramicro penetrometer, are regarded as C and D, respectively.
