Protons are the next big thing when it comes to fuel cell technology. The subatomic exchange produces power on a scale that challenges contemporary solid-state fuel cell technology, used to help power space shuttles. <\/p>\n\n\n\n

To realize the proton-based technology sooner, an international team of researchers have developed a hybrid material that effectively transports protons at high temperatures and humidity \u2014 two major challenges in past attempts.<\/p>\n\n\n\n

The results were published on April 19 in ACS Applied Materials & Interfaces<\/em><\/a>, a journal of the American Chemical Society.<\/p>\n\n\n\n

The team, led by the University of Tokyo in Japan, focused on a material called polyoxometalates (POMs), which they previously fabricated into a composite with another polymer and compounds to help provide structural stability.<\/p>\n\n\n\n

\u201cPOMs are attractive as building blocks for the design and synthesis of new materials with desirable properties and functions \u2014 they can efficiently transport protons, for example, but only at low temperatures and in low humidity,\u201d said paper author Masahiro Sadakane<\/a>, professor in the Graduate School of Advanced Science and Engineering<\/a>, Hiroshima University. \u201cUnfortunately, a huge problem remained to be solved is that our composite decomposed at higher temperatures and humidity.\u201d<\/p>\n\n\n\n

To solve this problem, the researchers investigated how to better tune the composite by encapsulating positively charged ions in the material\u2019s internal cavities. Positive ions, known as cations, help balance negatively charged ions, known as anions, to stabilize conductivity in a material.<\/p>\n\n\n\n

They settled on incorporating europium, a metallic element that is solid at room temperature, into the material. Europium is particularly attractive to water molecules, which brings external oxygen into the material. Protons move through the system by attaching to the oxygen. The more oxygen, the more proton-conductive the process is.<\/p>\n\n\n\n

\u201cOur goal is to produce stable high proton-conductive materials,\u201d said paper author Sayaka Uchida, associate professor in the Department of Basic Science, School of Arts and Sciences, The University of Tokyo. \u201cThrough fine control of the components, we produced such a material.\u201d<\/p>\n\n\n\n

The material continued to demonstrate high proton conductivity at temperatures of 368 degrees Kelvin (202.73 degrees Fahrenheit) and 50% humidity. The researchers plan to increase the stability and proton conductivity further.<\/p>\n\n\n\n

\u201cWe plan to increase the stability and proton conductivity so that this material can be used as an electrolyte in fuel cells, enhancing their performance,\u201d Sadakane said. \u201cThis work could provide guidance for the design of solid-state proton conductors.\u201d<\/p>\n\n\n\n
