Fuel cells are electrochemical cells that converts the chemical reaction energy of a continuously supplied fuel and an oxidant into electrical energy. In colloquial usage, fuel cell is usually a hydrogen-oxygen fuel cell. Continue reading →

A problem in today’s technical utilization of fuel cells are economic aspects. Conventional centralized produced hydrogen is produced and liquefied in large electrolysis plants. The necessary energy for this process comes from the general power grid and thus relies mainly on fossil fuels. Continue reading →

Hub motors are electric motors that produce the moment directly to the wheel axles. Therefore, conventional, highly wear-loaded components such as gears, shafts ( kardan , drive … ) , differentials etc. are no longer required. Continue reading →

Shipping is by far the largest commercial carrier in the world economy. The transport costs ( € / t * km ) are very small in relation . Under increasing cost pressure and the price increases of refined products in the last 10-15 years, the travel speed is reduced ( the consumption of sea-going vessels increases exponentially with speed ) and high-sulfur-contaminated crude oils for burning on ocean-going are used.
