1 FUEL CELLS Mikael Paronen FD, Avdelningschef Företagsekonomi. Medie och teknik ARCADA

2 SIDA2 Fuel Basics  Electrochemical conversion  No thermal limitations; Carnot cycle  No burning; electrochemical reaction  H 2 + ½ O 2 => H 2 O // 1.2 V  Losses: kinetics and resistivity ====>  U: V

3 SIDA3 Fuel cells; structure

4 SIDA4 Fuel cell: operational principle

5 SIDA5 Fuel Cell Future  Free from hazardous emissions  Low green house emissions  Solar energy supported  Energy efficiency  Energy density  Cost effective  Mobile

6 SIDA6 Why now???  Invented 1839  Applied by NASA 1960s  Need for new materials  Lack of cheap energy

7 SIDA7 Selection and types of fuel cells  High power = high temperature  Fuel cells classified by electrolyte  Polymer electrolyte: max 100 C  Alkaline C  Phosphoric acid C  Molten carbonate C  Solid oxide C

8 SIDA8 Portable cells  Based on polymers as electrolytes  Fuel alternatives:  Hydrogen  Methanol  Formic Acid  NaBH 4

9 SIDA9 Solar cells vs. fuel cells Solar Cells:  “From light to Electricity”  Power output 300 W/m 2  Dependent on light Fuel Cells:  From Fuel to Electricity  Power density max 10 kW/m 2  Dependent of fuelling Connection between solar cells and fuel cells: reversible cells// electrolysis cells (light =>electricity => electrolysis of water => hydrogen gas => storage => electricity)

10 SIDA10 Fuel Cell project at Arcada  Focused on small devices ( W)  Scope in component integration  Separate projects in the development of  Electrode/catalyst layer  DC/DC Converters  Composite Materials (electron conductive)  Management of Fuel and Waste at the Anode side

11 SIDA11 Lab excursion  Walter Virta (elektroteknik): fuel cell basics and testing  Maia Mangdalezha: Thermodynamic and mathematical optimization of the anode side  Mikael Paronen: materials development needed

12 SIDA12
