    Abstract: There are provided a method and an apparatus for generating a current command value for tracking the maximum power point of a solar energy generating system. The apparatus includes: a voltage detector detecting a voltage input into the flyback power converter; a first calculator calculating an output power from the detected input voltage; a second calculator calculating a power variation based on the calculated output power and a voltage variation of the input voltage; and a current command value generator generating a current command value for tracking the maximum power point of the solar cell module from the calculated voltage variation and the calculated power variation. Accordingly, a current command value after calculating an output power may be generated with only a voltage detector, without a current detector, thereby reducing the costs of a solar energy generating system by decreasing the costs for a high-priced current detector, and simplifying circuit.

    Abstract: The present invention relates to an electrolyte-impregnated, reinforced matrix for molten carbonate fuel cells and a manufacturing method thereof. According to the invention, the electrolyte-impregnated matrix, which comprises both the electrolyte and the reinforcing particles including a metal and an oxide, is manufactured by adding the electrolyte, as required per unit cell of a fuel cell, and the reinforcing particles including the metal and the oxide, to a slurry during the matrix preparation step, and subjecting the resulting slurry to a tape casting process. By doing so, the matrix stacking operation is facilitated, and the matrix manufacturing process is simplified. In addition, cracking caused by the difference in thermal expansion coefficient between an electrolyte sheet and the matrix can be suppressed, and thermal shock occurring during operation of the fuel cell stack can be reduced, thus improving the performance and lifetime of the fuel cell.
