Abstract
According to the present invention, in an electrode ink, ionomers are adsorbed around a catalyst carrier to form a primary aggregate which does not aggregate with another catalyst carrier, and catalyst carriers aggregate together to form a secondary aggregate. In this method for determining a good-quality product of an electrode ink, the modulus of elasticity of the electrode ink is detected. Furthermore, on the basis of the modulus of elasticity, the states of the primary aggregate and the secondary aggregate in the electrode ink are estimated, and, if the contained amount of the primary aggregate is greater than that of the secondary aggregate, the electrode ink is determined to be good-quality.
