Optimization of the performance of fuel cell stacks using an ultrasonic humidifier

PEMFC technology opens up many possibilities for clean and sustainable energy generation. In the heart of this technology lies a fuel cell stack, which consists of many cells connected in series. Achievement of optimal working conditions of the fuel cell stack could be a complicated task that requires optimized humidity and temperature. In this work by varying these parameters , achievement of improved overall cell performance, a decrease of voltage disbalance between individual cells and an increase of operational stability is expected. The goal of the present bachelor work is to assemble a research fuel cell stack of and to investigate the influence of air humidification via an ultrasonic fog generator on the performance of the stack.
