Photosynthesis: Photosynthesis is the process by which plants, some bacteria, and some protists use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the “fuel” used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. They release molecular oxygen and remove
Polymer electrolyte membrane (PEM) fuel cells—also called proton exchange membrane fuel cells—deliver high-power density and offer the advantages of low weight and volume, compared with other fuel cells. PEM fuel cells use a solid polymer as an electrolyte and porous carbon electrodes containing a platinum catalyst. They need only hydrogen, oxygen from the air, and water to operate and do
Hydrogen Fuel cell oil powered cars extract hydrogen from water Hydrogen Energy is alternative name for Fuel Cell. Hydrogen (H element) usually called as the perfect fuel. It is a significant reserve on earth (Ex. Water) and it is exhaustible. The utilization of hydrogen is compatible with nature, instead of intrusive. We will never run out of Hydrogen. After all
Introduction to Fuel Cell A fuel cell is an electrochemical mechanism that produces power without combustion by joining hydrogen and oxygen to generate water and heat. The voltage created by a single cell is typically rather small (< 1 volt), so many cells are connected in series to create a useful voltage. Hydrogen fuel cells are feasible to modernize the
