Step 1

They are durable and both have been in we source of fuel and oxygen or air to sustain the chemical reaction whereas in a battery the chemical preteen in the 0 camera batteries works that Cell phone / Digital camera batteries The most commonly used cell phone I digital are lithium-ion batteries and nickel metal hydride batteries and lithium Re gar Rechargeable batteries fur digital cameras are called Nickel metal hydride. There batteries can be recharged hundreds of 야 times with a basic charger. The other type of battery used is lithium-ion puck. These packs are rechargeable bort usually have a custom Changes that only for type. The most obvious difference between Lithium ion and Micheet metal hydride batteries ū the material wed to store power Lithium ion batteries are made of highly reactive Lithium which can slove to of energy - Nickel metal hydride batteries we hydrogen to store energy with nickel and another metal lid on the hydrogen ions. Nickel Metal Hydride batteries are dress expensive technology. Nickel Metal Hydride batteries are and heavier than lithium-ion batteries Lithium ion and Nickel Metal Hydride batteries can actually sold a but the lithium ion cells can be similar amount of power, carbon and lot keeping a larger . Charged and discharged more rapidly. Both types of batteries has an hydride for years in various applications, this is one area where Nickel Metal advantage . Some lithium-ion batteries don't long in extreme temperatures A fuel cell is a device that convert the chemical energy from a fuel into electricity through a chemical reaction of positively charged oxygen • oxidizing agent fuel different from batteries in requiring a continues last as ions with or another hydrogen cells areas there an the oxygen react battery react with each other to generate an emf fuel cells con produce electricity contentiously for as long inputs are supplied There are many types of fuel cells, but they all consist of anode, a cathode and an electrolyte that allows positively charged hydrogen ions to move between the two side fuel cell The anode and cathode contain Catalyst that came q the fuel to undergo oxidation reactions that generate positively Chan-gel hydrogen ions and electrons. The hydrogen lone are drawn through the electrolyte after the reaction. At the same time, electron are drawn from the anode to cathode though an external circuit, producing direct Merreurt electricity: At the Cathode, hydrogen tons, elections and to form water. The energy efficiency of a fuel cell in generally between 40-60% Wind Turbine Blade The materials wed for the wind turbine balder the i Because of composite mat-val, blades can spin faster and Capture coinds at lower velocity.
