solar panel business requires sophisticated technologies and greater investment, which brings high barriers to entry. But once entered, the possibilities of others entering would be low. However, there are many substitutes to the solar panel industry, such as the fossil fuel. Because there are many alternatives, the buyers’ power is high – they can switch to other industry at any moment.
fuel cell applications, including :
proton exchange membranes
conductive bipolar flow plates
cell plate coatings
Polymer behave like molecular sieves in the solid state
Internal surface area is wide
Pore size can be controlled up to nano-scale
Organic polymer is good one to be PIMs
Operate at very low temperature
High efficiency of a PEM ; 40 to 60 percent
Compact and light uni
Fuel cells chemically combine the molecules of a fuel and oxidizer without pollution of traditional combustion.
In a fuel cell, the electricity is generated directly as an electrochemical device and therefore, there is no high-temperature step as normal burning. This direct conversion of chemical energy to electrical energy is more efficient and generates much less pollutions than do traditio
to the original substance; water after being used. We can expect that after 2010, the cost of hydrogen as one of the resources should be lower than that of fossil fuel. Fuel cell is the bright prospective technique and it already spreads out in many industrial field like hydrogen fueled car. However, although our interest in fuel cell is increasing, the stage of the development is still slight. T
