METHOD AND APPARATUS FOR MEASURING DISPLACEMENT OF A FUEL CELL STACK DURING ASSEMBLY

摘要

A method of testing the assembly of a fuel cell stack comprising a plurality of fuel cells (for example, solid polymer electrolyte fuel cells) applies a compressive force to the stack and measuring the displacement of the stack i n response to the applied force. An apparatus for testing the assembly of a fu el cell stack comprises: (a) a compression device for applying a compressive force to the stack; (b) at least one load monitoring device for measuring th e applied force; and (c) at least one displacement monitoring device for measuring the displacement of the stack in response to the applied force.
