Renewable Energy Rundown: Hydropower

This is the third part in a SaveOnEnergy series discussing the ins and outs of different forms of renewable energy. Much like the history of wind power, people have been harnessing the power of water for centuries – a form of energy now known as hydropower. In fact, up until 2019, hydropower was the largest source of total U.S. renewable...

Fuel Cell Stack Temperature in Mid-to-High Temperature Fuel Cells

There is an acute need for the development of long-lasting, efficient and portable power sources for further technology improvement in automobiles, commercial electronics devices, military and stationary applications. These systems all require the power source to be energy-efficient, and able to operate for long periods of time without...

Water Management For PEM Fuel Cells

One of the greatest challenges associated with PEMFCs is the water balance in the fuel cell stack. As the chemical reaction occurs in each cell, water is generated. Depending upon the load and the operating conditions, there is a tendency for the fuel cells to both flood and dry-out. The water content in the...

Considerations for Micro and MEMs Fuel Cells

The design elements of a micro or MEMs fuel cell stack are the same as a larger fuel cell stack, except that there should be special considerations for...
