Abstract
Vehicle powertrain technologies for transportation will see a dramatic change in the future. To limit climate change, Zero Emission Vehicles will be necessary to lower Greenhouse gas emissions like CO2. To become independent from limited fossil fuels, alternative fuels like hydrogen will play an important role especially for interurban and long-distance travelling. These cars will run on Low-Temperature PEM fuel cells. To improve their durability, they have to be protected from contamination. Recent examples are the Cathode Air Filter and the Ion Exchange Filter. Cathode Air Filters separate particles and noxious gases that would poison the fuel cell catalyst from cathode air. Ion Exchange Filters are designed to keep conductivity of fuel cell cooling liquid low to avoid shorts. The presentation gives information about megatrends and upcoming alternative powertrain technologies, the function of fuel cells, and how to protect them from contamination.
