Abstract
A fuel supplying apparatus is proposed, having a fuel and a polymer to control rate of fuel release. When the fuel supplying apparatus is applied in a fuel cell, the rate of fuel release is controlled using the polymer to maintain fuel concentration in the fuel tank of the fuel cell within a certain range without additionally installing devices and tubes for controlling fuel concentration. Thus, operation efficiency of the fuel cell is improved.
