These features, along with high-precision processing technologies have helped to miniaturise these products. The micropump is 6.0mm in diameter and 24.0mm in length, the microvalve measures 3.5mm in diameter and 10.3mm in length. The products are small but ensure high functionality by incorporating fluid, structure and magnetic field analysis simulations. Development will contribute to enhanced miniaturisation, an indispensable prerequisite for portable device fuel cells. Through the optimal design of diaphragm operations, valve configuration to prevent fluid backflow, materials and layout, Alps has achieved the effective control of larger amounts of fluid in a smaller chassis for its micropump. The unit also employs low-voltage electromagnetic drive systems, which contribute to easy control and fuel cell system engineering.
