Presenatation on fuel cell by karambir singh
Fuel cells are efficient power generators that convert chemical energy directly into electrical energy without moving parts. They have no significant energy loss, making them a clean and lightweight alternative power source. Fuel cells use liquid fuel like methanol and oxygen to produce electricity through a catalytic reaction that generates carbon dioxide and water vapor as exhaust. They work by oxidizing fuel at the anode to generate protons and electrons, with the protons passing through a membrane to the cathode where they combine with oxygen and electrons to form water, producing electricity in the process. Fuel cells can charge batteries automatically when the voltage drops and switch off once charged to provide reliable continuous power and extend battery life.

- 2. What are Fuel Cells ? • A fuel cell is an alternative power generator. • It transforms chemical energy into electrical energy directly, with no intermediate steps, no moving parts, and with no significant loss in energy, making it a particularly efficient source of power. • A huge amount of patented innovation has gone into making fuel cells a marvel of miniaturization, that are lightweight, but high-powered & long-lasting performers. • These fuel cells lead the field in fuel cell systems for off-grid power & mobile/static applications for Mission Critical Communication / IT/ Optronics/ Sensors/ Auxilary Power etc.

- 5. How it Works • Fuel cells charge batteries fully automatically. • The integrated charge controller permanently monitors the charge level of batteries. • When the battery voltage drops below a predefined level, the fuel cell starts automatically and recharges the battery. • Once the battery is charged, it switches off again. This results in reliable, continuous power, reduces the amount of batteries needed, and extends the lifetime of the batteries since deep discharge damages are prevented. Via an inverter, you can also operate 230 V devices.
- 6. Fuel Cells and the Hybrid Principle Fuel Cells • Fuel cells use liquid fuel. • Every Fuel Cell employs DMFC (Direct Methanol Fuel Cell) technology which transforms methanol directly into electrical current. • That's a real advantage, especially for mobile applications, because liquid methanol is easy to transport anywhere in practical fuel cartridges. Hybrid Principle • Fuel cells also work in hybrid with other power generators. • For example, if a fuel cell is connected to an application that also has solar to it, the fuel cell only charges the battery if solar does not deliver enough energy – due to bad weather.
