Hydrogen Summary Essay Example for Free

heat content Summary Essay* This is how hydrogen fire cells work1. Gas stored in tanks 2. Atoms reach anode 3. perish hydrogen ion and a free electron 4. Ion goes through electrolyte layer 5. Hydrogen ion passes, but free electron does not 6. Free electron runs through outside circuit from anode (-) to cathode (+) 7. Current of electrons creates electricity 8. Hydrogen ion enters cathode and combines with oxygen to become water which is better for the ecosystem because water vapor is not dangerous.* Why hydrogen as fuel? Efficient not expensive to fill and it gives you more range. Emission Conscious Hydrogen fuel cell cars release water vapor back in the atmosphere and dont damage it by releasing C02 just like the other fuels. Fueling Up/Range Since hydrogen is stored and highly monotonic tanks it can hold more than any other fuel and has a bigger range. Global Economic Competitive Edge Hydrogen is not as expensive as gasoline and it would cost you about of the money that y ou used to fill your car with gasoline to fill your car with hydrogen.* Better than other fuels Hydrogen VS Ethanol * Ethanol releases CO2 while hydrogen releases water vapor * Ethanol competes with the food producers(corn in the US, sugar cane in Brazil)and hydrogen doesnt compete with anyone. * Ethanol is inefficient to produce while hydrogen is efficient. Hydrogen VS biodiesel * Biodiesel solidifies in cold temperatures and it is harder to travel through the tubes(high viscosity) while hydrogen doesnt solidify.* Biodiesel releases the to the highest degree C02 out of all the fuels. Hydrogen releases water vapor * The range for biodiesel cars is 10% less than propanol cars . Hydrogen cars have 25% more range than biodiesel cars and 15% more than propanol cars. Hydrogen VS propanol * Propanol has problems in high climates due to viscosity and the fuel solidifying while hydrogen cars dont have problems with this. * Propanol releases C02 in the atmosphere, hydrogen releases water va por. * The range for a propanol car is 15% less than a hydrogen car.
