Providing a fuel cellsupport systemof pumps, blowers, sensors, and controls for maintaining fuel rates, electric current load, gas and liquid pressures, and fuel cell temperature remains a major engineering design challenge. Significant improvements in the service life of these components under adverse...
from the exhaust substances in the gas-liquid separation tank142to flow and to be cooled through a gas-phase flow pipe144and a liquid-phase flow pipe146, respectively. The fuel cell main body120also includes a controller150which can control various types of pumps within the fuel cell system...
The system can pump out 2.5 watts of power, making them suitable for smart phones, small digital cameras, GPS units, and cell phones that typically use 5-volt USB chargers. Expected pricing for the Hydrofill and related components wasn't immediately available....
Small portable electrical and electronic devices have typically used batteries for power. However, conventional batteries have limited energy storage capacity. Thus, applications like professional video cameras, laptop computers, and cell phones often require longer runtimes than batteries can provide. ...
