Scientists are trying to give the fuel cell to build 'highway'

Perhaps one day, our phone or laptop battery by charging, but no longer add & other; Fuel & throughout; Several times, standby time can increase, the performance will be better. It may seem a little weird, and this can add & other anytime and anywhere; Fuel & throughout; The battery is related to the national economy and people's livelihood is one of the important research direction in the field of renewable energy. Tianjin university institute of mechanical combustion learn foreign professor Michael & middot; state key laboratory of Cover ( Michael D. Guiver) A study and associate professor of Yin Yan is expected to be the idea pushed forward.

as a plasma TV and LCD TV, plasma really than LCD? Not necessarily, but plasma disappear, because all the people in the industry to do LCD, plasma on the industrial chain lost competitiveness & throughout; , based on this kind of crisis consciousness, Daniel li for single crystal called for on the one hand, on the one hand, lead the team to expand photovoltaic industry chain downstream.

now the research team has been successfully prepared a novel composite proton exchange membrane, the orientation of orientational alignment with the membrane surface direction through the proton channel. Applies the proton exchange membrane fuel cell, as in a battery internal build up a & other; Highway & throughout; Short path, the realization of the proton efficient transmission, greatly improved the power output of proton exchange membrane fuel cell.

human is in an era of energy change. Fuel cell is known as the fourth generation after power, hydropower, nuclear power development technology, is a kind of fast and reliable energy conversion device, can be directly convert chemical energy of fuel into electricity.

in recent years, the research findings of proton exchange membrane fuel cells are widely used in daily life, science and technology products, national defense construction and so on many aspects, such as mobile phones and laptop computers and other portable electronic devices, electric cars, regional power stations, submarines, the power of the space shuttle. Proton exchange membrane fuel cell is to show the world the great application value and development prospects.

in proton exchange membrane conduction, the path the shorter, the save time, save time means that the efficient, effective connection with cost and performance. If can in proton exchange membrane is built along the membrane surface through direction of twists and turns, short path proton channel, proton transfer efficiency will be improved to a great extent. Inspired, and usually used in the preparation of proton exchange membrane solvent casting membrane method is different, Michael & middot; Cover with Buddha Yin Yan associate professor team to join the auxiliary of the magnetic field in the process of the membrane, using iron cyanide coordination polymer and phosphotungstic acid formation of paramagnetic complexes, in proton exchange membrane type through the face direction to construct the orientation of short path efficient proton transport channel.

the good news is, through the iron cyanide coordination polymer and phosphotungstic acid compound, the membrane method at the same time solve the water-soluble phosphotungstic acid easy to seep scientific problem in the polymer matrix.

in addition, through the iron cyanide coordination polymer iron cyano group's REDOX cycle, the proton exchange membrane can within the battery consumption unceasingly in the operation of the system of free radicals, and makes the application of membrane improved durability. With the existing of proton exchange membrane and other hydrocarbon as the standard for industrial Nafion membrane, compared to 212 the orientation model of proton exchange membrane in proton conductivity, fuel cell power output and service life has more obvious advantages and potential.
