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.
A hydrogen fuel cell electric vehicle is powered by a group of individual fuel cells, known as a fuel cell stack.The stack is designed to contain enough cells to provide the necessary power for the automotive application.A fuel cell stack produces power as long as fuel is available, similar to a combustion engine.uel cell electric vehicles achieve the beneficial characteristics of both conventional and battery electric vehicles. The combination of these desirable characteristics makes fuel cell electric vehicles an attractive advanced vehicle option for drivers that value long range, fast refueling, and zero-emissions.
