  • 1. FUEL CELLS• amangeldiuly nurlybeknurlybek.amangeldiev@gmail.com
  • 2. PLAN• HOW DOES IT WORKS?• TYPES• USES• ADVANTAGES/DISADVANTAGES
  • 3. STRUCTURE
  • 4. TYPES1. Solid-oxide fuel cells — SOFC2. Proton-exchange membrane fuel cell — PEMFC3. Reversible Fuel Cell4. Direct-methanol fuel cell — DMFC5. Molten-carbonate fuel cells — MCFC6. Phosphoric-acid fuel cells — PAFC7. Alkaline fuel cells — AFCetc…
  • 5. USES1. Land vehicles2. Airplanes3. Boats4. Submarines5. Fueling stations6. Providing power for base stations or cell sites7. Off-grid power supply8. Distributed generation9. Fork Lifts10. Emergency power systems are a type of fuel cell system, which may include lighting, generators and other apparatus, to provide backup resources in a crisis or when regular systems fail. They find uses in a wide variety of settings from residential homes to hospitals, scientific laboratories, data centers, telecommunication equipment and modern naval ships.
  • 6. USES1. An uninterrupted power supply (UPS) provides emergency power and, depending on the topology, provide line regulation as well to connected equipment by supplying power from a separate source when utility power is not available. Unlike a standby generator, it can provide instant protection from a momentary power interruption.2. Base load power plants3. Electric and hybrid vehicles.4. Notebook computers for applications where AC charging may not be available for weeks at a time.5. Portable charging docks for small electronics (e.g. a belt clip that charges your cell phone or PDA).6. Smartphones with high power consumption due to large displays and additional features like GPS might be equipped with micro fuel cells.7. Small heating appliances8. Space Shuttles
  • 7. ADVANTAGES• Environmental Reasons Chemical energy of fuel and oxidizer – Driving force Combustion chamber Fuel cell – Lowered emissions Heat – Less noisy• Higher quality Turbine or engine – Can be programmed for 99.999% uptime Mechanical energy• More reliable – On site Electric generator – No movable parts Electric current
  • 8. DISADVANTAGES• Hydrogen: – Not readily available, must use other energy sources to convert – Infrastructure not in place – Difficult to store/distribute• High Capital Cost• Non-technical barriers – Could have dramatic impact
