Publikováno v: Karimäki, H, Nikiforow, K, Keränen, T & Ihonen, J 2011, ' PEMFC anode side system optimization studies ', Fuel Cell Seminar 2011, Orlando, FL, United States, 31/10/11-3/11/11 . < http://www.malmokongressbyra.se/kongress/download/1111_kajnikiforow.pdf >

PEMFC systems are usually operated in dead-end mode with hydrogen recirculation and periodic purge. This enables high hydrogen utilization, but also makes the system prone to accumulation of inert gases, condensed water and fuel contaminants. Optimiz
