The work presents the techno-economic analysis of stationary and mobile battery storage systems in local electricity markets. The interaction between energy storage and the energy management used in the peer-to-peer network is specifically discussed. To evaluate the results, both the economic attractiveness of the selected energy management and the lifetimes of the battery storage systems are… [read more]

Proton exchange membrane (PEM) fuel cells generate electrical energy without direct CO2 emissions from the electrochemical reaction of hydrogen and oxygen to water. Thereby, PEM fuel cells distinguish themselves among others in high power densities and high flexibility. In June 2021 two new fuel cell related research articles of the Chair of Technical Electrochemistry were published in the Journal… [read more]

The electrolysis of water by means of a proton exchange membrane (PEM) is a very promising technology for the production of green hydrogen. A new publication now shows ways to modify these membranes, which are commonly used in industry, to improve their usability and quality. [read more]
