Fuel cells and the electric motor are examples of highly-efficient, electric drive trains. Electric vehicles are expected to one day outstrip sales of combustion engines vehicles. Innovative technologies such as fuel cells, electric motors and electric vehicles will influence our future mobility. The market for electric vehicles boasts the most potential.
Fuel cells, electric motors and electric vehicles are currently experiencing a breakthrough. Fuel cells are being used in new applications such as automobiles or laptop computers. Like electric vehicles, fuel cells are still in the development phase however. The potential is far from being exploited. Because a genuine fuel cell boom is anticipated, mass production is already underway. Like fuel cells, the application potential for electric motors and electric vehicles is still in its infancy stage. The discovery of the relationship between magnetic fields and electricity laid the foundation for the electric motor, and thus the electric vehicle. The electric motor that eventually resulted from this discovery is driven by the Lorentz force, which is the force on an electric charge as it moves through a magnetic field. The development of traditional technologies such as fuel cells and the electric motor has led to a rise in environmentally-friendly electric vehicles. Hybrid vehicles are still dominating the market in the segment for environmentally-friendly automobiles however. Utilizing a combination of combustion and electric motors, hybrid vehicles are slimmed-down versions of the electric vehicle.
Fuel cells are based on the principle of a galvanic process. The composition of a fuel cell is influenced by both electrodes. The fuel cell energy stems from the electrode potential, which is created by the charging of the anode and cathode. The charging results in a potential difference in the fuel cell, which is eventually transformed into electric energy. From its discovery, to today's high-technology status, the fuel cell has experienced an astounding development. Fuel cells are already being used in a variety of applications today. But its impressive career is far from over. Because of their simple operation, the use of fuel cells in electric vehicles represents the market of the future.
Theelectric motor began as an electromechanical transformer. As the description implies, the electric motor is capable of transforming electricity into mechanical energy. The electric motor functions by transforming its mechanical force into motion. Like fuel cell technology, the electric motor is a popular drive train alternative in electric vehicles. The development of the electric motor as a drive train for electric vehicles is still a work in progress however. The first genuine electric motor was produced as early as 1834. Today, state-of-the-art, innovative technologies are still based on discoveries made by researchers nearly 200 years ago, as illustrated by the examples of the fuel cell, electric motor and electric vehicle.
While electric motors and fuel cells were originally used in industrial machine applications, electric vehicles are the technology of the future. At the beginning of their development, electric motors were initially used in locomotives . At this point, the focus is on the development of roadworthy electric vehicles. The key drivers of modern research into the electric vehicle are the electric motor's high degree of efficiency and low CO2 output, two factors that are behind current efforts to combat energy resource and climate change issues. The major issue is energy storage , which is the why researches are focused primarily on this aspect. For this reason, hybrid model electric vehicles - the combination of electric and combustion motors - are still in their infancy stage.
Automotive Engineering highlights issues related to automobile manufacturing - including vehicle parts and accessories - and the environmental impact and safety of automotive products, production facilities and manufacturing processes.

There have been fixed standards regulating technical cleanliness inspections of component parts in the automotive industry for over a decade. These are codified in the German Association of the Automotive Industry (VDA) vol. 19.1. So that companies can inspect components in accordance with policy, laboratory managers should be qualified “Technical Cleanliness Inspectors”.
To this end, Fraunhofer IPA has been offering the required training for over ten years now. Given that demand abroad has risen substantially on account of the...15.09.2015 | Read more

Plug-in hybrids have low fuel consumption, but require more costly parts than cars with a regular combustion engine. During development, the optimal cost balance must be calculated, which has been extremely time consuming to date. Now researchers at Chalmers University of Technology have developed a new method that dramatically reduces the time needed for these calculations.

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.
A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
