Becker and his co-workers used a single flow-through dc-excited microplasma reactor to generate hydrogen from an atmospheric pressure mixture of ammonia and argon for use in small, portable fuel cells.[8] Lindner and Besser experimented with reforming model hydrocarbons such as methane, methanol, and butane into hydrogen for fuel cell feed. Their novel microplasma reactor was a microhollow cathode discharge with a microfluidic channel.
