Title: Fuel cell
Inventor: YOSHINAGA ISAO
IPC: H01M8/02
Filed: 1985-08-13
Abstract: PURPOSE:To widen groove dimension accuracy and reduce machining cost by forming zigzag gas passage in a gas separating plate. CONSTITUTION:Grooves (gas passages) 8, 8a are formed zigzag without connecting straight gas inlet and gas outlet to widely supply gas to electrode reaction surface. By reducing the number of grooves (gas passages) in a gas separating plate 7 to 1/10-1/50 compared with the conventional cell, flow rate is increased and flow is converted from laminar flow into turbulent flow. Since gas flow rate in the groove is proportional to 2.7 power of the equivalent diameter of the groove, the machining accuracy of groove dimension is widened compared with fourth power of laminar flow and making cost of the groove is reduced. In addition, gas is widely supplied to electrode reaction surface regardless of reducing the number of grooves.
