To generate hydrogen-rich gas which is supplied to a fuel cell stack of a fuel cell power plant, a reformer generates reformate gas comprising hydrogen from methanol, and a carbon monoxide oxidizer oxidizes carbon monoxide from the reformate gas by an action of a catalyst incorporated therein. A first passage, a second passage, a third passage and a fourth passage are respectively defined in an inner surface of the hollow pipe and communicate with each other. The invention also relates to a method of preparation of the stabilized compositions of troponin. The kit further comprises a package containing the artificial nails, the dispenser, and the applicator cap.
