Abstract
In the present invention, an electrode ink has formed therein: a primary aggregate in which ionomers are adsorbed around catalyst carriers, and as a result thereof, aggregation between catalyst carriers is prevented; and a secondary aggregate that is formed when catalyst carriers aggregate with each other. In an electrode ink quality determination method, a measurement system detects an index that correlates with the amount of the primary aggregate and the amount of the secondary aggregate in the electrode ink. An information processing device: estimates the conditions of the primary aggregate and the secondary aggregate in the electrode ink on the basis of the index detected; and determines that the greater the amount of the primary aggregate included is, relative to the amount of the secondary aggregate, the better the quality of the electrode ink is.
