Fuel Cell Technology Heat Balance

From a slideshow by Convion (Finland) on its fuel cell technology.

Using a feed of 8,42 kg natural gas per hour with an energy content of 114,75 KW (based on the lower heating value) the CHP equipment yields 59,5 KW electric energy and heat. Biogas or hydrogen can also be used as fuel.

Electrical efficiency is between 53 and 65% net AC, the total energy efficiency is larger 85%.
