Why are fuel cells better for many applications than batteries?
Fuel cells and batteries both use silent chemical reactions to release electrons and provide useful electricity. A battery converts a fixed amount of chemicals that are stored inside the battery into electricity. This means that a battery eventually “goes dead” and you either throw it away or need to recharge it “on the grid”. However, a fuel cell does not need to be recharged and never stops providing power, so long as the “fuel” is available. When used in long runtime applications, the UltraCell XX25™ fuel cell has the advantage of being two to three times lighter than batteries. An UltraCell system can be deployed in almost any application where off-grid power for extended periods is needed. Since fuel cells are good at providing steady power or current, and batteries are effective in providing sharp peaks in power, UltraCell’s systems are easily hybridized with batteries to take advantage of the dual benefit.
