Iranian Scientists Use Nanotechnology to Produce Hydrogen-Making Electrolyzers
“The hydrogen electrolyzer consists of several membranes. Each of these membranes has specific features based on the tasks defined for them. One of these membranes is hydrogen-loving and the other is hydrogen repellent. By spraying nanoparticles on the membrane coating, when water enters the device through electric current, the efficiency of the device and the final output are increased based on the hydrogen-loving and hydrogen-phobic properties,” Amir Ali Amir Khalili, the managing director of the knowledge-based company active in the field of clean energy, told ANA.
“The device operates in such a way that water enters the device through electric current, and after processing by bipolar membranes (hydrogen-loving and hydrogen-repellent) inside the device, oxygen and hydrogen are released from the device,” he added.
“Hydrogen is widely used in industries like steel recovery, methanol production, urea production and petrochemical industry,” Amir Khalili added.
In addition to designing the membrane used in the device, determining the size of hydrogen output from the device is also one of the most important knowledge-based capabilities of the company’s experts, he said, adding that only two countries of the world, the US and Japan, have access to this know-how.
In a relevant development in January, specialists of an Iranian knowledge-based company stationed at Isfahan Science and Technology Park had also succeeded in indigenizing hydrogen generators for hydrogen separation in pharmaceutical industry.
"Hydrogen generators are a proper alternative to hydrogen capsules. Hydrogen capsules have many risks, including the risk of explosion and fire,” Kourosh Jiani, a technical expert at the Iranian knowledge-based company, told ANA.
He added that the hydrogen generators electrolyze water, noting, “Pure water without ions enters the device and the device separates the water. Finally, the separated hydrogen and oxygen are the output of this device.”
Elaborating on applications of the separated hydrogen, Jiani said, “The hydrogen separated in the device after the drying process can be used in the pharmaceutical industry, laboratories and forensic medicine.”
Jiani said that before indigenization of the device in Iran, it was imported from countries like Germany and the US.
