Inkjet printing in polymer electrolyte membrane electrolysis

In proton exchange membrane fuel cells (PEFCs), the catalyst and electrolyte loading have been shown to have an important effect in the performance and efficiency of the device. On the contrary, literature analyzing the effect of the fabrication method, catalyst and ionomer loading in proton exchang...
