Christian Gutsche was born on 6th December 1985 in Eisenach (Germany).
Having made his Bachelor degree in physics and biology at the University of Bremen he graduated as Master of Science in physics at the Universities of Bremen and Oldenburg with the specialisation on physics of renewable energies and solid state physics. During his studies he received a scholarship of the Rosa Luxemburg Foundation. In his master thesis he studies chalcopyrite solar cell-like systems with the methods of electrical detected magnetic resonance and electron spin resonance at the Helmholtz Centre Berlin (supervisors: Prof. Klaus Lips, Dr. Thomas Unold) and with spatial resolved photoluminescence at the University of Oldenburg (supervisor: Prof. Gottfried H. Bauer). „I see my social responsability as physicist in supporting the decentralized development of renewable energies." He is active in the field of solidarity economy since 2006. He co-initiated some citizen-financed solar power plants with some hundred kWp power and supports renewable energy projects in the north and west of Cameroon. He led several seminars on solidarity economy. In 2012 he initiated a community supported agriculture project in Bremen (100 members in december 2012) and started working conceptionally on perspectives of community supported agriculture.
Short description of the doctoral thesis:
„Development and characterisation of bifunctional Platinum-Iridium-baed catalysts for Vanadium-Air-Redox-Flow Batteries"
Vanadium-Redox-Flow Batteries have as cheap electrochemical energy storage system a high potential for decentralized storage of electricity from renewable sources. In this systems electrical energy can be stored in chemical form in two Vanadium containing electrolyte tanks. One innovative approach for further ressource and cost savings is the Vanadium-Air-Redox-Flow Battery. Here one electrolyte is replaced by oxygen from air and water as reaction partner. One crucial step to increase the effíciency of this system is the optimisation of the oxygen reaction kinetics with adequate catalysts. The development of bifunctional catalysts consisting of materials, that have a high catalyticactivity for both charging and discharging reactions makes the use of one bifunctional reaction unit instead of one charge and one discharge unit possible leading to further cost reduction. The aim of the PhD work is to colloidchemically prepare nanoparticles as mono- and bifuncitonal catalysts, to study them and to optimise them concerning their catalytic activity and durability. The advantage of collodchemical synthesis is mainly a high control over structural and functional properties of the catalysts. Additionally to the scholarship from the Reiner Lemoine Foundation Christian Gutsche has one more scholarship from the „Stiftung der Metall-Industrie im Nord-Westen".
