One of the most promising alternatives is hydrogen fuel cells, which use hydrogen to directly generate electricity via a reaction with oxygen, but the race is still very open as to which hydrogen ...

Hydrogen fuel cells are highly efficient. They use hydrogen and oxygen to produce electricity and heat. Electrolysers reverse this process. They split water into hydrogen and oxygen with the help of ...

According to many experts, we may soon find ourselves using fuel cells to generate electrical power for all sorts of objects we use every day. A fuel cell is a device that uses a source of fuel ...

Here the authors directly observe space-charge-induced electric fields at yttria-stabilized zirconia grain boundaries, revealing how space charge layers corelate with grain boundary orientations ...

Various types of fuel cells exist, but the one automakers are primarily focusing on for fuel cell cars is one that relies on a proton-exchange membrane, or PEM. In the generic PEM fuel cell ...

A new approach to elucidate the operation and control of Polymer Electrolyte Membrane (PEM) fuel cells is being developed. A global reactor engineering approach is applied to PEM fuel cells to ...

Buoys and floats are designed to float on the surface of a body of water, or are supported below the water’s surface to mark a location. They are used in marine navigation, boat mooring, nautical ...

Hydrogen-oxygen fuel cells are an alternative to rechargeable cells and batteries. In a hydrogen-oxygen fuel cell, hydrogen and oxygen are used to produce a voltage. Water is the only product.

We're more than happy to enjoy a ride over the water, but that's one of the more puzzling facts about boats. How exactly do boats float whenever other items that weigh far less than them can sink ...

Stay up to date with the latest in developments from the world of yachts, speedboats, underwater vehicles, and more – if it floats or dives, you’ll find it here.

Many of the financial ratios used in the fundamental analysis include terms like outstanding shares and the float. Let's go through the terms shares and float so that next time you come across ...
