A fuel cell is an electrochemical cell that produces power through a reaction, triggered in the presence of an electrolyte, between the fuel (on the anode side) and an oxidant (on the cathode side). The reactants flow into the cell, and the reaction products flow out of it, while the electrolyte remains within it. Currently a couple of fuel cells are available, which can be allocated to different fuel cell families as shown in the table below.

Introduction

A fuel cell is an electrochemical cell that produces power through a reaction, triggered in the presence of an electrolyte, between the fuel (on the anode side) and an oxidant (on the cathode side). The reactants flow into the cell, and the reaction products flow out of it, while the electrolyte remains within it. Currently a couple of fuel cells are available, which can be allocated to different fuel cell families as shown in the table below.

Type Efficiency Operating temperature
Gas engines (25) 30 - 100 proved and tested Power, heat, emission reduction since 1996 over 100 units in operation
Boilers / Burners - monovalent (20) 25 - 100 proved and tested Heat, emission reduction since 1980th
Boilers / Burners - additional (20) 25 - 100 proved and tested Heat, emission reduction since 1900 on mines
CMM flaring 20 - 100 proved Emission reduction used on landfills
Liquified Natural Gas - LNG 50 - 100 tested LNG, emission reduction 660 Mio. m³ in 2006 (US-market)
VAM utilisation 0,2 - 1,2 demonstration - some are in operation
Gas turbines / mikro turbines 40 - 100 demonstration - -
