• Hydrogen produced from waste water using microbial electrochemical cells

    We human beings have sure underestimated and ignored the use of all the waste we produce, and are slowly realizing just how much of an impact recycling could have on our lives. Well, waste water has its uses too, and we’ve just realized that. Creating hydrogen to power up hydrogen fuel cells can be a pain in the backside, though researches have found a novel way to do so. Arizona State University’ Biodesign Institute came up with a way to use wastewater as a feedstock to generate hydrogen for fuel cells. These microbial electrochemical cells, better known as MXCs, use bacterial respiration to liberate electrons which can generate current and ultimately electricity.


    These devices with a few tweaks here and these can also carry on electrolysis to help out with hydrogen production. This does away with the need to use natural gas and fossil fuels used to manufacture hydrogen. Technology is sure looking towards a greener horizon today.
