In contrast to the classical, direct reaction, where water is formed under a huge release of energy in form of heat (imagine a hydrogen-oxygen gas mixture that is ignited), a fuel cell has two chambers, containing the two compounds.<\/p>\n<p>In the middle of these chambers, there is a membrane, that allows diffusion of hydrogen but not of any other molecule.

This leads to a decrease of hydrogen concentration at the membrane and causes more hydrogen molecules to move towards the membrane. By the diffusion of hydrogen to the oxygen containing chamber, there is some electrical voltage generated at the membrane.

In this case, we will focus on thermal analysis techniques.<\/p>\n<p>Some hydrogen storage applications run at high pressure sometimes exceeding 100 bar so that pressurized analyzers are useful. Additionally, all analysis techniques need precautions due to the high reactivity of hydrogen to oxygen\/air. In consequence all devices have to be equipped with safety feature avoiding the risk of explosions.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-30e35301 elementor-invisible elementor-widget elementor-widget-text-editor\" data-id=\"30e35301\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;fadeInUp&quot;,&quot;_animation_delay&quot;:500}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-74132 size-large aligncenter\" src=\"https:\/\/www.linseis.com\/wp-content\/uploads\/2025\/01\/Tabelle-Wasserstoff-Applikationsoberseite-1024x265.png\" alt=\"\" width=\"1024\" height=\"265\" srcset=\"https:\/\/www.linseis.com\/wp-content\/uploads\/2025\/01\/Tabelle-Wasserstoff-Applikationsoberseite-1024x265.png 1024w, https:\/\/www.linseis.com\/wp-content\/uploads\/2025\/01\/Tabelle-Wasserstoff-Applikationsoberseite-300x78.png 300w, https:\/\/www.linseis.com\/wp-content\/uploads\/2025\/01\/Tabelle-Wasserstoff-Applikationsoberseite-768x199.png 768w, https:\/\/www.linseis.com\/wp-content\/uploads\/2025\/01\/Tabelle-Wasserstoff-Applikationsoberseite-1536x398.png 1536w, https:\/\/www.linseis.com\/wp-content\/uploads\/2025\/01\/Tabelle-Wasserstoff-Applikationsoberseite-2048x531.png 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2ced376 elementor-invisible elementor-widget elementor-widget-text-editor\" data-id=\"2ced376\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;fadeInUp&quot;,&quot;_animation_delay&quot;:500}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>Application example<strong>: Hydrogen release from surface storage<\/strong><\/h3>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4d86afbb elementor-invisible elementor-widget elementor-widget-text-editor\" data-id=\"4d86afbb\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;fadeInUp&quot;,&quot;_animation_delay&quot;:500}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The following application example shows where thermal analysis and material science equipment is used in the field of hydrogen energy and fuel cell technology:<\/p><p>Hydrogen storage can be performed as surface adsorption, pore adsorption or chemical uptake.
