Recently, fuel cells have been developed in many laboratories as a high-efficiency and environment-friendly power source. In order to improve their performance, it is necessary to investigate the gas or liquid flow pattern in a micro-channel with sharp turn corners in a fuel cell. So, in this study, the velocity distribution of the liquid flow in a micro-channel was numerically analyzed using authors' CFD code based on the finite element method and also it was measured by means of the line LDV. Using these two approaches, it has been found that the calculated flow pattern between two sharp turn corners in the channel reveals the existence of separation and stagnation regions and the calculated and measured velocity profiles show a similar trend.
