¶ … Fuel Cell Technology
There are over 600 million motor vehicles in the world today. If present trends continue, the number of cars on Earth will double in the next 30 years." ("Cars Emit")
As the demand for energy increase and resources, such as fossil fuel, decrease alternative must be sought. Of these alternatives, hydrogen fuel cell technology, in automotive applications, has significant benefits and is now technologically feasible. Given this knowledge, it is imperative that we begin to set up the infrastructure necessary to utilize this technology.
I have studied this topic over the last three years, and the advancement of the technology has become increasingly exciting. What was once a dream is now a reality.
I'm going to provide you first with an overview of how fuel cells work and then describe for you the benefits of the use of fuel cells, including why hydrogen is the best choice. And, in the end, I will recommend a course of action for the beginnings of the infrastructure that is sure to be an entirely new chapter in our global history.
To understand why hydrogen fuel cells hold the key to combating our pollution problems, one must first understand how fuel cells work.
How fuel cells work
With a proton exchange membrane fuel cell, there are four basic elements.
The anode is the negative post of the cell and "conducts the electrons that are freed from the hydrogen molecules so that...
Different Fuel Cell Technologies U.S Department of Energy (2010) provides the description of different fuel cell technologies. The fuel cell technologies are differentiated according to their efficiency, operating temperatures, costs and application. The classifications are based on 6 major groups: Alkaline fuel cell (AFC), Phosphoric acid fuel cell (PAFC), Solid oxide fuel cell (SOFC), Molten carbonate fuel cell (MCFC), Proton exchange membrane fuel cell (PEMFC); Direct methanol fuel cell (DMFC). Alkaline fuel cell (AFC) The AFC generates electrical power
I do that every day. But I've never done that with a car. I buy what I need to look successful. Besides, how would I ever calculate a payback when I have no idea what gasoline will cost in the future?" A few said with apparent certainty, "one year" or "two years." However, when we inquired where the number came from, they simply asserted that they spent lots of
As the term suggest, liquefied natural gas (LNG) is natural gas that has been reduced to a liquid by cooling it to minus 161°C thereby eliminating oxygen, carbon dioxide and other unwanted components to achieve almost pure methane (Liquefied Natural Gas 2012). According to one LNG producer, "In the liquefaction process, impurities are removed from the gas before it is cooled. The cooling of natural gas to -162°C causes it
The energy it stores (?180 Wh kg?1) at an average voltage of 3.8 V is only a factor of 5 higher than that stored by the much older lead -- acid batteries. This may seem poor in the light of Moore's law in electronics (according to which memory capacity doubles every 18 months), but it still took a revolution in materials science to achieve it. Billions of lithium-ion cells
Business & Society Questions Business & the Environment The UPS Green Fleet A United Parcel Service (UPS) store is located in Chambersburg, Pennsylvania. The company has established a number of initiatives that are environmentally friendly, not the least of which is the conversion of a portion of their fleet to hybrid electric vehicles. In fact, as of February 2011, the UPS delivery fleet using alternative fuel and technology had driven 200 million miles
Wireless Broadband Technology Overview of Wireless technology Presently it is quite evident to come across functioning of a sort of wireless technology in the form of mobile phone, a Palm pilot, a smart phone etc. With the inception of fast connectivity in the sphere of commerce it is customary and useful to operate from central locations communicating with the remote branches, conducting conferences in remote places, discussing with every body at every
