摘要 |
A metal separator for fuel cells formed with a metal plate and provided between cells accumulated, in which the metal plate is formed like trapezoidal irregularities to separate channels for a fuel gas from ones for an oxidant gas. Slope portions are formed after forming uniformly and thinly wall thickness of both upper and lower flat portions or either of the upper or the lower flat portion to 90% or less of that of the metal plate to be formed to obtain trapezoidal irregularities by forming flat portions which contact upper and lower cells and slope portions which interconnect the upper and the lower flat portions.
