electric arc rocket

I've read somewhere on the internet that some Germans have made an engine which heats up hydrogen by passing it through electrical arc discharge. It was claimed 16 km/s exhaust velocity. Does anyone here have more information on said engine?
from wikipedia, arcjet:
"In Germany, researchers at the University of Stuttgart's Institute of Space Aviation Systems have been looking into these challenges for years and have developed various hydrogen-powered arcjet engines capable of power outputs from 1 to 100 kW. The heated hydrogen reaches exit speeds of 16 kilometres per second (9.9 mi/s). An arcjet-propelled test satellite by the name of Baden-Württemberg 1 (BW1) is scheduled to go to the Moon. Baden-Württemberg 1 would use polytetrafluoroethylene PTFE propellant.[5]"

Arc jets have been around forever. They're the easiest form of electric propulsion to make.
