Flow regimes of fuel cell separators with improved moisture balance

摘要

The technology disclosed herein relates to a fuel cell comprising a gas diffusion layer and a separator plate.Separator plate 119 forms at least one gas guide flow region together with gas diffusion layer 114.At least one passage web 200 of the separator plate 119 has an end 210 having an upper surface 202 and an end surface 201.The end surface 201 is formed so as to divide the flow S10 into contact with the end surface 201 of the passage web 200 in the first direction R10 into two divided portions S21 and S22.The end surface 201 is provided so that the fluid F of the flow S10 abutting the end surface 201 adjacent to the upper surface 202 is changed so that the fluid f is greatly separated from the upper surface 202 than before the change.
