Design Analysis of Fullbridge Converter on Proton Exchange Membrane Fuelcell

Fuelcell is an electrochemical energy conversion device that converts hydrogen that reacts with oxygen into water, simultaneously producing electrical and thermal energy in a process. Fuelcell is a simple form of technology such as a battery that can be refueled to get its energy back, in this case the fuel is hydrogen. The implementation of this study simulated the Fuelcell and added the use of a Fullbridge DC - DC type power converter that uses isolated which is able to raise the voltage with a voltage ratio that can maintain its efficiency well. This study presents fuelcell and fullbridge modeling to obtain high efficiency using PSIM applications. And performed openloop integration on fuelcell with AVISTA PEM Fullbridge SPECS. In this trial, researchers varied the fuelcell temperature using 3 temperature variations, namely 60°C = 333.15K, 80°C = 353.15K and 100°C = 373.15K. From this temperature variation, it produces increased power and produces a fairly good efficiency of 82 – 84%. As well as keeping a constant voltage of 311 volts with an error of 1.5%. With this, humans can be used to become an alternative source of energy needed, one of which is in the automotive world.
