High-temperature protonic conductors

18.04.2006


The research group GMBM (Biomimetic and multifunctional materials) of the University of Seville is working on the creation of fuel batteries with protonic conductor membranes. The National Aeronautics and Space Administration (NASA) is funding this line of research.



The director of GMBM, Julián Martínez Fernández, has been collaborating with the NASA-Glenn Research Center (in Cleveland, Ohio) for thirteen years. The University of Seville’s project, funded with 200,000 €Euros, consists of developing materials that can produce non pollutant energy.

This source of clean energy is in high-temperature protonic conductors. Fuel batteries are the nucleus of the energy future based on hydrogen, more cleanness and efficiency, and an essential part of these batteries are protonic conductor membranes.


In an interview for Andalucía Investiga, Julián Martínez said that ‘as working temperature increases the efficiency of batteries, the idea is that such membranes are made of materials that are very resistant to high temperatures’. The GMBM is working ‘on the synthesis of these membranes, in their characterisation’, and by means of several agreements, ‘the application membranes are tested in the real world’.

The specific utility of their use in remote production systems, solar stations and eolic plants, lies in their performance in the reverse order. This way, the fuel cells can separate the surplus molecule in the two elements that make it up, that is, water is divided into hydrogen and oxygen, and the energy of the former is accumulated.

Hynergreen, a research division of the Abengoa group, is taking part in the implementation of the new system. It is intended that it replaces the traditionally used materials – plastic polymers-, the only problem being that they are less resistant to high temperatures.

On the contrary, the multifunctional ceramics developed by the University of Seville overcome this limitation. During an interview for Andalucía Investiga, the director of GMBM confirmed that its conductive capacity stays ‘over 1,400 degrees centigrades’.

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
