Investigation of the prospect of energy self-sufficiency and technical performance of an integrated PEMFC (proton exchange membrane fuel cell), dairy farm and biogas plant system

Guan, Tingting; Alvfors, Per; Lindbergh, Göran - In: Applied Energy 130 (2014) C, pp. 685-691

A PEMFC fuelled with hydrogen is known for its high efficiency and low local emissions. However, the generation of …-CHP with a stack having an electrical efficiency of 40% generates 360MWh electricity and 680MWh heat per year, which is enough … to cover the energy demand of the whole system while the total efficiency of the PEMFC-CHP system is 82%. The integrated …
