A bipolar plate, an important component of the fuel cell

by admin on 21-06-24

A bipolar plate, an important component of the fuel cell Bipolar plates Bipolar plates are made of graphite or metal; they evenly distribute the fuel and the oxidant to the cells of the fuel cell. They also collect the generated electric current at the output terminals. In a single-cell fuel cel...

Vacuum Pumps work

by admin on 21-06-21

When does a Vacuum Pump benefit an engine? A vacuum pump, in general, is an added benefit to any engine that is high performance enough to create a significant amount of blow-by. A vacuum pump will, in general, add some horse power, increase engine life, keep oil cleaner for longer. How do Vacuum...

How Redox Flow Batteries Work

by admin on 21-06-17

How Redox Flow Batteries Work The separation of power and energy is a key distinction of RFBs, compared to other electrochemical storage systems. As described above, the system energy is stored in the volume of electrolyte, which can easily and economically be in the range of kilowatt-hours to te...

HOW TO MAKE A SILICON WAFER

by admin on 21-06-07

HOW TO MAKE A SILICON WAFER A wafer is a slice of silicon roughly 1 millimeter thick that has an extremely flat surface thanks to procedures that are technically very demanding. The subsequent use determines which crystal growing procedure should be employed. In the Czochralski process, for examp...
