Abstract
An apparatus of solid oxide fuel cells (SOFC) is provided. The SOFCs generate power and are grid-tied. The apparatus comprises a power-generating side; and a grid-connecting side using an elementary household power management. The apparatus solves problems like low voltage, high current, voltage oscillation, voltage dips, long generator-starting time, etc. The apparatus is not only used as a stable power supply (base load), but also helps adjust the regional peak electricity demands. The features include the following: 1. A grid is tied, where output power does not pass through a direct-current boost converter and, thus, has no loss from it. 2. Injures, including voltage oscillation and sudden unloading after dumping, are reduced for avoiding further damages to cell sheets. 3. With the coordination of elementary power management and the integration of grid, the limitation of long-awaiting generator-starting time is crossed out and convenience of immediate power use is achieved.
