Gas diffusion electrodes and operating conditions for electrochemical energy storage applications
… world today faces two contradictory challenges: climate change and energy security. Interestingly, both challenges can be potentially addressed by targeting atmospheric CO2. The global demand for energy has increased due to population growth and most of this demand is met by the dwindling resource …
