What is Hydrogen Fuel Cell?   A fuel cell is an electrochemical energy conversion device, similar to a battery in that it provides continuous DC power, which converts the chemical energy from a fuel directly into electricity and heat. When operated directly on hydrogen, the fuel cell produces energy with clean water as the only by-product. Unlike a battery, which is limited to the stored energy within, a fuel cell is capable of generating power as long as fuel is supplied. As such, the fuel cell system also has similarities to an internal combustion engine, except that it operates very efficiently at low temperatures and with minimal moving parts.   Although hydrogen is the primary fuel source for fuel cells, the process of fuel reforming allows for the extraction of hydrogen from more widely available fuels such as natural gas and propane or any other hydrogen containing fuel.      

How fuel cell works?   Fuel cell are composed by the proton exchange membrane, catalyst layer, cathode (gas diffusion layer) , anode (gas diffusion layer) and collector plates. Proton exchange membrane and catalyst layer compose membrane electrode. Membrane electrode, cathode and anode gas diffusion layer compose MEA. Finally MEA and two collector plates compose a single cell.   Gas(hydrogen and air) through the collector plate channel into both sides of the electrodes of proton exchange membrane. Through this channel hydrogen flow the anode coated with platinum catalyst, separated into hydrogen protons and hydrogen ions. Free electrons flows into the external circuit and produces an electric current; proton via electrolyte membrane move into the cathode. Oxygen in the air, the electrons and protons in the external circuit are reacted in the anode, producing  pure water and releasing heat.   Number of single cell formed fuel cell stack by splicing to provide the necessary power. Single cell `s open circuit voltage is about 1V, full load is about 0.6V. Single cell compose fuel cell stack in series to provide the necessary output voltage. Fuel cell`s output current was proportional with the effective area, therefore, fuel cell stack can via splicing geometrically to generate the required output voltage, current and power.

Features  

Simpler Structure, Smaller Size and Lighter in Weights  Thanks for the unique air cooled technology; the fuel cell system can be operated without humidification system for air and hydrogen as well as water-cooling system. For instance, weight of a 4 kW fuel cells system with PASH technology is just about 1/3 weight of conventional water-cooling and pre-humidification fuel cell system.

Higher Reliability  Simplized structure of fuel cell system is the result of minimization of the quantity of accessories which loweres risk of system failure and increases the reliability of the whole system.

Competitive Cost  Fewer accessories contributes a lot to the cost control of the whole fuel cell system.

Simpler Control System  It is not necessary to control anything, except for electromagnetic valve and fan, when the fuel cell system works. The whole fuel cell system is easily applied into other products due to the simple control system.

Higher fuel efficiency  Simplized Auxiliary system cosumes less power generated by stack and increases the fuel efficiency. Normally the auxilliary system only consumes 0.5%-3% of gross power generated by stack.

Better Environmental Adaptability and excellent performance of CCM  The CCM has striking performance, 0.65V/800mA, without humidification. The CCM has excellent environmental adaptability. Our fuel cells can start up and work under environment temperature of -10°C as well as 20%-95% RH without any assistance of external power sources.
