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.
Claims15
A fuel supplying apparatus in a fuel tank of a fuel cell, comprising:
- a fuel;
- and
- a cross-linked membrane for encapsulating the fuel and isolating the fuel from a fuel solvent in the fuel tank,
- wherein the cross-linked membrane is only permeable to the fuel and is a single-layered cross-linked membrane allowing the fuel to permeate in one direction;
- and
- wherein the cross-linked membrane serves as a one-way gate to the fuel encapsulated therein, such that the fuel is released at a rate controlled by diffusion.
