Potential of ORC Systems to Retrofit CHP Plants in Wastewater Treatment Stations
(International Centre for Sustainable Development of Energy, Water and Environment Systems, 2013)
Wastewater treatment stations take advantage of the biogas produced from sludge in anaerobic digesters to generate electricity (reciprocating gas engines) and heat (cooling water and engine exhaust gases). A fraction of ...

Layer by Layer Segmentation of Water Distribution from Neutron Imaging of Large Scale Cells
(Electrochemical Society Inc., 2015)
We present a method for distinguishing liquid water content in the different layers of a polymer electrolyte fuel cell (“anode flow channels”, “cathode flow channels”, and “GDL/MEA”) from through-plane neutron imaging. ...
