The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life. Organisms can be classified as unicellular (consisting of a single cell; including most bacteria) or multicellular (including plants and animals). Humans contain about 10 trillion (10) cells. Most plant and animal cells are between 1 and 100 µm and therefore are visible only under the microscope.
The cell was discovered by Robert Hooke in 1665. The cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that all cells come from preexisting cells, that vital functions of an organism occur within cells, and that all cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells.
The word cell comes from the Latin…

The Newly Redesigned 2008 Honda FCX Fuel Cell Car

Posted on by admin

Hydrogen fuel cell vehicles are considered as zero emission vehicles. These vehicles combine hydrogen fuel and oxygen from the air to produce water and electricity. The electricity is then used to power the electric motor which powers the vehicle.honda-fcx-dash

Honda motors has developed a concept fuel cell car called the “Honda FCX” which will become a limited production car in 2008. Honda has equipped the FCX with a fuel stack and an ultra capacitor along with high pressure hydrogen tanks. The fuel cell stack serves as the main power source while the ultra capacitor serves as the storage unit for supplemental power.

The Honda fuel stack consists of the PEMFC (Proton Exchange Membrane Fuel Cell) and has a total maximum output of 86kW. The water produced when hydrogen and oxygen are combined, is used in the humidification system. The fuel cell system is located under the floor and the high pressure hydrogen tanks are positioned under the rear seat. The ultra capacitor is positioned at an angle behind the rear seat to ensure that luggage space is not lost from the trunk.

During startup and acceleration, the ultra capacitor assists the fuel cell to power the electric motor. During slowdown, the ultra capacitor recovers energy and stores it for future use. While the vehicle is stopped, the ultra capacitor provides energy to power the A/C, Radio and other electrical components while shutting the power from the fuel stack to the motor.honda-fcx

The latest generation of Honda FCX is about two times more efficient than it’s hybrid counterparts. Honda has also redesigned the fuel cell stack to be V shaped to allow quick recovery of water generated during the electricity production. It is about 20 percent lighter and 30 percent smaller, while producing 14kW additional power. Honda has also added an auxillary litium ION battery.

The vehicle top speed is about 100 mph with a range of 354 miles on one tank. Large scale production of this car is limited by the number of hydrogen refuelling stations that will be built over the next few years. Overall, Honda seems to have made fantastic progress in building a highly energey efficient car of the future.
