Unfortunately, they haven&amp;#39;t really take off (excuse the pun) due to their high cost, poor lifetime and slow transient performance. 1...</description><dc:language>en-US</dc:language><generator>Telligent Community 12</generator><item><title>RE: Hydrogen Fuel Cells!</title><link>https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/hydrogen-fuel-cells</link><pubDate>Wed, 04 Dec 2013 17:56:12 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:b4ca1355-2901-4e44-ae33-ccd280064233</guid><dc:creator>Former Member</dc:creator><slash:comments>1</slash:comments><description>&lt;p&gt;&lt;span class="j-excerpt-slug"&gt;Hydrogen fuel cells without infrasturcture why buy one.&amp;nbsp; Nobody buys them so no infrastructure.&amp;nbsp; Chicken and egg.&amp;nbsp; How do you boot strap?&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=16719&amp;AppID=84&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item><item><title>RE: Hydrogen Fuel Cells!</title><link>https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/hydrogen-fuel-cells</link><pubDate>Tue, 03 Dec 2013 09:38:59 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:b4ca1355-2901-4e44-ae33-ccd280064233</guid><dc:creator>rodreig89kishore</dc:creator><slash:comments>2</slash:comments><description>&lt;p&gt;I like the idea of hydrogen to be used as fuel but its combustible nature is too risky.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;Still it is a clean fuel that we need to tap into.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;If I am not wrong liquid hydrogen does work as fuel but again the same issue .&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;ITS RISKY.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;I however think that still it can be used.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;The best ways of using hydrogen as fuels that I can think of is if as already provided today is cryogenic chambers.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;I propose minute hydrogen packets the size of gelatin pills.&lt;/p&gt;&lt;p&gt;One pill can store as much compressed liquid hydrogen it can as specified.&lt;/p&gt;&lt;p&gt;And all the pills will be kept together in a huge chamber instead of the whole content being put in the cryogenic chamber.&lt;/p&gt;&lt;p&gt;A small auto dropping system can be made which will release one pill at a time to outside temperatures and when hydrogen pill react to regular temperatures at a fast rate we know what happens Combustion.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;I will try to formulate a system for this.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;But need to work on trapping compressed liquid hydrogen in small gelatin packets.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;That I leave it in your hands.&lt;br /&gt; &lt;/p&gt;&lt;p&gt;The system however can be made according to safety standards and hydrogen explosion force and thereby viable. to all &lt;span&gt;[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-b4ca1355-2901-4e44-ae33-ccd280064233/contentimage_5F00_1.png:16:16]&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;TC till then&lt;br /&gt;&lt;span&gt;[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-b4ca1355-2901-4e44-ae33-ccd280064233/contentimage_5F00_1.png:16:16]&lt;/span&gt;&lt;br /&gt;P.
