An Ethernet Host Adapter is a host adapter for Ethernet networking and is also called by a variety of other names such as: Ethernet Adapter, Network Adapter, LAN adapter, Ethernet Card, Network Card, Network Interface Card (usually abbeviated NIC) and so on.
In addition to electricity, fuel cells produce water, heat and, depending on the fuel source, very small amounts of nitrogen dioxide and other emissions. The energy efficiency of a fuel cell is generally between 40â60%, or up to 85% efficient in cogeneration if waste heat is captured for use. The fuel cell market is growing, and in 2013 Pike Research estimated that the stationary fuel cell market will reach 50 GW by 2020.
Is it possible for vehicles powered by hydrogen fuel cells to reduce the pollution in the air? FREDERIC J. BROWN/AFP/Getty Images One of the most important benefits of a hydrogen economy is that fuel cells are nonpolluting. No carbon emissions are produced when electricity is generated in a fuel cell. A hydrogen fuel cell produces two byproducts -- heat and water. If every vehicle on the road were powered by a hydrogen fuel cell, the familiar clouds of smog that hang over many U.S. cities, most of which comes from vehicle exhaust, would largely disappear.
