Scarcity of resources is becoming increasingly important in today's society. For this reason, new, sustainable and environmentally- friendly technologies from different sectors of our so-ciety are and will be the focus of many research areas. Students should be made aware of this rapid change in technology, especially by natural science teachers, and a responsible approach should be supported. In this thesis, the technical background on fuel cells and "green energies" is to be illuminated on the one hand and, on the other hand, a detailed analysis of the "low cost microbial fuel cell" experiment as well as a short explanation of the subject of NAWI ed-ucation at austrian schools respectively. This diploma thesis is divided into four main areas: the analysis of the term NAWI at austrian schools, the topic and definition of "green energy", the technical background of the different types of fuel cells and the "low cost microbial fuel cell"- students experiment and the specialist didactic analysis and embedding of this experi-ment in the education shall of secondary level I and II. In addition to these points, a detailed examination of the microbial fuel cell self- constructed in the experiment as well as all the components and Chemicals.
