We propose a highly efficient active direct-methanol fuel cell system for portable application in this paper. The system is composed of a fuel cell stack, mechanical parts, a smart battery, and circuit parts. The mechanical parts consist of several pumps, a mixer, a liquid separator, and heat exchange modules. The battery enables the operation of the mechanical parts and powers the output load during...
Fuel cell is a kind of new power source which has advantages of high energy density, clean and quiet. To overcome the disadvantages of fuel cell such as low energy density and low response speed, hybrid structure including fuel cell and battery is often used. In this paper, a novel control strategy is proposed for the DC/DC converter which converts power from fuel cell to load. This new strategy is...
