PROBLEM TO BE SOLVED: To grasp a distribution state of hydrophilic group in a reaction layer of a fuel battery.SOLUTION: Sulfonic acid group bonded to hydrophilic group in a reaction layer is subjected to dying by allowing the sulfonic acid group to be bonded to the hydrophilic group (sulfone group) contained in the reaction layer of a fuel battery, and by loading into the reaction layer metal ions, such as ruthenium ions, capable of forming a nitrosyl complex together with the sulfonic acid group. When the hydrophilic group is aggregated, the sulfonic acid group bonded thereto is also aggregated. By subjecting the sulfonic acid group to dying with ruthenium, the ruthenium is also aggregated. This is observable with an electron microscope. The sulfonic acid group has an affinity for the hydrophilic group by bringing NOx gas into contact with the reaction layer. |
