Abstract

In this paper, a fuel cell battery charger system, which is capable of bi-directional power transmission without built in battery, has been designed and fabricated. Performance and states of the notebook battery in bi-directional power transmission using the manufactured system have been tested. Before initializing the fuel cell charging system for 1 minute, the system received 10 W of electric power from notebook battery. Then the fuel cell charging system has been normal charging to notebook battery by 50 W. As a result of the experiment, the state of the notebook battery discharged less than 5% at the initial charging time, but then it has been charged. This results proves bi-directional power transmission in notebook computers increase the availability of fuel cell chargers.
