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.
