The utility model discloses a many functional test flow field board, including the flow field edition of books body, air inlet, gas outlet, runner, node switch, spine, flow field edition of books body quadrate, the runner of the flow field edition of books body is mutually perpendicular slot runner, the spine sets up in the middle of every two sets of mutually perpendicular's runner, set up at least one node switch in the runner, inlet set sets up the right downside at the flow field edition of books body in the upper left side of the flow field edition of books body, gas outlet, the air inlet communicates with each other with the runner, and the gas outlet communicates with each other with the runner. The utility model discloses simple reasonable, easily operation, only need in test to adjust the open -closed state of node on the different runners, can realize the interconversion in seven kinds of different forms flow fields, avoid assembling the trouble that a plurality of battery brought for the fuel cell who tests different flow fields, the utility model discloses through equipment once alright be used for testing the fuel cell in different flow fields, test, research and the optimization of comprehensive seven kinds of different flow fields fuel cell performances of completion.
