Current collector plate for fuel cell for e.g. electric vehicle, has electrically conductive material coated along stacking axis of cells, where edges of current collector plate are tapered to obtain reduced thickness

摘要

The plate (50) has an electrically conductive material of constant thickness coated along a stacking axis of cells of a fuel cell stack. The conductive material forms a plane formed at an end of the stack for collecting current of a fuel cell, where edges (52) of the current collector plate are tapered to obtain reduced thickness. A flat surface is in contact with the last cell of the stack, where the edges are tapered on the side opposite to the last cell, and cross-section of the collector plate is in trapezoid form. Independent claims are also included for the following: (1) a method for dimensioning tapered edges of a current collector plate (2) a fuel cell.
