However, researchers are also working on making hydrogen fuel cells from algae. One way of doing it is to combine microbial fuel cells with microalgal photobioreactors. It’s also worth noting many types of microalgae have diatoms, which can turn accumulated fats and cellulose into hydrogen. ...
Denmark’s current consumption of gray hydrogen is amongst the lowest in Europe. This will increase in the future as renewable hydrogen is needed to decarbonize the transport sector. However, with Denmark’s ambitious hydrogen and wind plans, the country is poised to becomea net exporter of re...
“Fuel cells that are light and small have been proposed as energy conversion devices in various portable appliances, such as cell phones, cameras, and notebook computers. Since the space and weight of the devices are key requirements, the energy density they provide should be maximized,” said...
National Laboratory have developed a new class of hydrogen fuel-cell catalysts that exhibit promising activity and stability. The catalysts are made of low-cost nonprecious metals entrapped in something called a heteroatomic-polymer structure, instead of platinum materials typically used in fuel cells....
(PhysOrg.com) -- As fuel cells are becoming more popular due to their potential use in applications such as hydrogen-powered vehicles, auxiliary power systems, and electronic devices, the need for the precious metal platinum is also increasing. In fuel cells, platinum is often used as the ca...
Spain's Cidetec Technology Center announced Thursday it has designed a prototype for a motorized bicycle powered by fuel cells. Officials said pedaling is assisted by a motor, powered by a fuel cell that only needs oxygen from the air and hydrogen contained under pressure in a small tank. ...

high energy-consuming enterprises must transition to green and low-carbon practices to survive. In 2020, the Pengfei Group proposed a 78 billion CNY investment in hydrogen for sustainable development. This proposal was based on the existing coke oven tail gas, renewable energy cells, and chemical ...
