Fuel cell and Hydrogen Energy project by Biswajit Mandal,Department of Chemical Engg,HIT,Haldia
Fuel cells are electrochemical devices that convert chemical energy in fuels into electrical energy directly, promising power generation with high efficiency and least environmental impact [4]. Because the intermediate steps of producing heat and mechanical work, typical of most conventional power generation methods are avoided. Fuel cells are not limited by thermodynamic limitations of heat engines such as the Carnot efficiency. In addition, as hydrogen is not chemically bound with carbon unlike other gaseous fuel, fuel cells produce only water and electricity without any pollutant. However, unlike batteries the reductant and oxidant in fuel cells must be continuously replenished to allow continuous operation. Fuel cells bear significant resemblance to electrolyzers. In fact, some fuel cells operate in reverse as electrolyzers, yielding a reversible fuel cell that can be used for energy storage. Though fuel cells could, in principle, process a wide variety of fuels and oxidants, most interest today are those fuel cells that use common fuels (or their derivatives) or hydrogen as a reductant, and ambient air as the oxidant. Most fuel cell power systems comprise a number of components:
Proposed deletion of Hydrogen Energy and Fuel Cell Research by Biswajit mandal,Department of Chemical, Engg, Haldia Institute of Technology,West Bengal,India
[edit]Hydrogen Energy and Fuel Cell Research by Biswajit mandal,Department of Chemical, Engg, Haldia Institute of Technology,West Bengal,India has been proposed for deletion. An editor felt this information might be based on your own conclusions or research, rather than published ideas. Please review Wikipedia:No original research for the relevant policy. If you can improve the article to address these concerns, please do so, citing sources.
If no one objects to the deletion within five days by removing the "prod" notice, the article may be deleted without further discussion. If you remove the prod notice, the deletion process will stop, but if an editor is still not satisfied that the article meets Wikipedia guidelines, it may be sent to Wikipedia:Articles for deletion for consensus.

- The deletion was contested, but the points of contention have not been resolved. Therefore, I have begun the process of nominating the article for deletion, as seen here: Wikipedia:Articles for deletion/Hydrogen Energy and Fuel Cell Research by Biswajit mandal,Department of Chemical, Engg, Haldia Institute of Technology,West Bengal,India. Please note that this process cannot be contested or the notification removed from the page until the AfD process has been concluded by a Wikipedia administrator. You are welcome to comment on the contents of the article and the process of the deletion on the above discussion page, and are encouraged to do thus. --Agamemnon2 08:32, 8 June 2007 (UTC)
Notification of speedy delete nomination on Fuel Cell Developed By Biswajit Mandal In India,Faculty of Chemical Engineering,Haldia Institute of Technology,West Bengal
[edit]A tag has been placed on Fuel Cell Developed By Biswajit Mandal In India,Faculty of Chemical Engineering,Haldia Institute of Technology,West Bengal, requesting that it be speedily deleted from Wikipedia. This has been done for the following reason:
Under the criteria for speedy deletion, articles that do not meet very basic Wikipedia criteria may be deleted at any time. Please see the guidelines for what is generally accepted as an appropriate article, and if you can indicate why the subject of this article is appropriate, you may contest the tagging. To do this, add {{hangon}} on the top of the page and leave a note on the article's talk page explaining your position. Please do not remove the speedy deletion tag yourself, but don't hesitate to add information to the article that would confirm its subject's notability under the guidelines.
For guidelines on specific types of articles, you may want to check out our criteria for biographies, for web sites, for bands, or for companies. Feel free to leave a note on my talk page if you have any questions about this. Agamemnon2 08:19, 8 June 2007 (UTC)
New editor?
[edit]Hi, it seems to me that you're a new editor to Wikipedia and may be confused about the process of writing an article. Wikipedia isn't a place for people, no matter how qualified or informed, to write about the subjects they know about it in the format you've chosen. That kind of essay material would go elsewhere. Instead, Wikipedia functions in a way that presents information on subjects in an individual fashion, preferably backed up with sources to indicate but the verifiability and notability. It can be pretty complex, but I don't think your method of contributing is going to be acceptable without changing your practices. I'm sure I'm not saying this very clearly, but if you've got any questions, I'll do my best to answer them. FrozenPurpleCube 01:10, 9 June 2007 (UTC)
Article creation
[edit]Please stop creating articles like the above mentioned (... by Biswajit mandal,Department of Chemical, Engg, Haldia Institute of Technology,West Bengal,India). They are not suitable for Wikipedia and will be deleted. Continuing to create such articles (on article pages or on talk pages) is a form of disruption which will not be tolerated. Please familiarize yourself with Wikipedia and the kind of articles we accept, and check out pages like WP:V, WP:NOT and WP:OR to learn some of our basic policies. Wikipedia is the encyclopedia anyone can edit, but Wikipedia is not the encyclopedia where everything is welcome. Fram 12:02, 14 June 2007 (UTC)
