A dishwasher basket for storing at least one valve of toddler training cups in a dishwasher for cleaning. To catalyze the electrochemical reaction in the fuel cell and reduce the likelihood of the anode of being poisoned by by-products from the eletrochemical reaction and impurities in the fuel, an anode material with molecular recognition sites for the fuel is used in the fuel cell. A holding circuit holds the voltage at the positive electrode terminal of the capacitor at a substantially fixed value by charging the capacitor with electric power supplied from the telephone lines in an off-hook state. Each one of the louvers includes a slat, an aperture corresponding therewith, and a receiving area positioned therebetween. The heat sink thermally contacts the second surface of the circuit board.
