Electric Cars Application
Application of FCV
(Fuel Cell Vehicles)
Structure of FCV
It runs on electricity generated by a reaction between hydrogen and oxygen in the air in a fuel cell.
It is an eco-friendly car that does not emit carbon dioxide while driving.
A characteristic of fuel cells is that hydrogen and oxygen react to generate electricity, and only water is discharged.
IGBT Power Module
IGBT stands for insulated-gate bipolar transistor. It is a core device of energy conversion and transmission.
It plays a vital role in electric vehicles and is the core technical component of equipment such as electric vehicles and charging piles. IGBT modules account for nearly 10% of the cost of electric vehicles and about 20% of the cost of charging piles.
Compared with various previous power electronic devices, IGBT has the following characteristics
1. High input impedance, universal low-cost driving circuit can be used;
2. High-speed switching characteristics, low loss in on-state.
3. Japanese brand distributor, corresponding to various models and needs, stable quality and supply.
IGBT Power Module
Hydrogen separation membrane module
It is a palladium alloy roll-plated hydrogen separation membrane for high purity hydrogen gas production and purification. Combined with unique metal filter technology with the characteristics of palladium alloy which only allows hydrogen particle to go through the filter. We have wound 10 - 20 μm thick palladium alloy membrane on dia 34mm, 300mm length cylindrical body. Completely wiping out any possibility of hydrogen gas leakage through unique welding, this allowed to produce ultra-high purity hydrogen. With the unique three layer structure which enhances sustainability and endurance have allowed to withstand its long-term application on commercial basis. All parts of this module are made of metals. Using welding, this allows to adapt to both small and large quantity order and even to massive plant application by alternating its parts combination.
Main Application
Main application for this hydrogen separation membrane module is PSA(Pressure Swing Adsorption) for hydrogen manufacturing machine at oil refinery, hydrogen manufacturing machine at hydrogen station that is drawing interest from the stand point of combustion-battery, fuel cell vehcle(FCV) development, hydrogen refinery process of house-hold combustion-battery, as well as ultra-high purity hydrogen gas refinery in semi-conductor industry.
Hydrogen embrittlement resistant stainless steel spring wire
The ductility of annealed type 304 stainless steel as measured by tensile elongation can be reduced substantially when high contents of hydrogen are absorbed. Therefore, the stainless steel to be used under low temperature, high pressure hydrogen atmosphere conditions such as hydrogen gas pressure control valve, filling nozzle, and the springs for fuel cell vehicles, hydrogen stations or fuel cell vehicles-related is in demand.
Features:
1. Good Hydrogen Embrittlement Resistance
Even under low temperature condition, its reduction ratio will not go down when carrying out ultra-low strain rate tensile test under high pressure hydrogen atmosphere.
2. High strength
Tensile strength equivalent to SUS304(WPB)
3. Good Spring Characteristics
Fatigue limit decline is kept to the minimum when carrying out fatigue test under hydrogen charged atmosphere.
Applications:
-
High Pressure Hydrogen Gas Pressure Control Valve (Main Stop Valve、Pressure Reducing Valve、Check Valve)
-
High Pressure Hydrogen Filling Valve
-
Spring for Fuel Cell Vehicles
-
Springs for Stationary Fuel Cell Systems
