In this article it is considered the results of experimental studies of solid oxide fuel cells and measured their currentvoltage characteristics(CVC). It is shown the block diagram of stand for the measurement of cells characteristics. According to the received data it is established and built the model of current-voltage characteristics and power characteristic using regression analysis. It is also determined an optimal level of loading of solid oxide fuel cells and it is calculated the measurement error of current-voltage characteristics.
