Although polymer electrolyte water electrolyzers (PEWEs) have been used in small-scale
(kW to tens of kW range) applications for several decades, PEWE technology for hydrogen …

When hydrogen is used for energy applications, then often elevated pressure is required, ie
up to 1000 bar for hydrogen refueling stations. When polymer electrolyte electrolyzers are …

A test bench for a polymer electrolyte water electrolysis (PEWE) cell for high pressure
operation of up to 100 bar in differential and balanced pressure mode is described …

An essential problem for the operation of high pressure water electrolyzers and fuel cells is
the permissible contamination of hydrogen and oxygen. This contamination can create …

Ultimately, fossil based energy sources are finite, and will eventually become a bottleneck in
sustaining energy-intensive activities of the human population. In this respect, and to battle …

In October 2011 the world's first hybrid power plant of the company Enertrag AG started its
operation in Dauerthal near Prenzlau, in the northeast of Berlin, Germany. With the …

With the impending ban on hydrazine in the space sector, a great interest in green
propulsion systems has developed. Therefore, the Institute of Space Systems of the …

Diese Dissertation fasst die Entwicklung eines Hochdruckelektrolysesystems mit einem
Betriebsdruck von 100 bar als Teil eines regenerativen Brennstoffzellensystems (RFCS) für …

Not only, but primarily to reduce the environmental damage and life cycle costs associated
with burning fossil fuels, capacities for renewable energy generation are being increasingly …

Depletion of easily accessed and light crude oil sources is shifting future crude oil supply to
less attractive heavier oil fractions. Vacuum residue, as the heaviest fraction found in crude …
