Being labeled as in the accompanying drawing: 1-clamping plate, 2-fuel cell plate, 3-bolt, 4-nut, 5-hydrogen input pipe, 6-oxygen input tube, 7-water delivery pipe, 8-minus plate, 9-positive plate, 10-hydrogen gas sensor, 11-data wire, 12-controller.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.Pem fuel cell stack with hydrogen gas sensor, constitute as shown in Figure 1, it is characterized in that: comprise at least more than one fuel cell plate 2 and be arranged on fuel cell plate 2 both sides and interconnective clamping plate 1, the inboard of the clamping plate 1 of both sides is respectively equipped with minus plate 8 and positive plate 9, clamping plate 1 outside of one side is provided with oxygen input tube 6 and hydrogen input pipe 5, clamping plate 1 outside of opposite side is provided with water delivery pipe 7, hydrogen input pipe 5 is provided with hydrogen gas sensor 10, and hydrogen gas sensor 10 connects controller 12 through data wire 11.
The profile of described hydrogen gas sensor 10 is annular, can be sleeved on easily on the hydrogen input pipe 5.
Described interconnective clamping plate 1 are through a plurality of bolt 3 interconnective clamping plate 1, and fastening by nut 4.
Described hydrogen gas sensor 10 can be semiconductor-type hydrogen gas sensor, electrothermic type hydrogen gas sensor or electrochemistry type hydrogen gas sensor.
Operation principle of the present utility model is as follows: fuel cell plate 2 is clamped in the centre of two clamping plate 1 by bolt 3 and nut 4, when hydrogen and oxygen are injected into fuel cell plate 2 by hydrogen input pipe 5 and oxygen input tube 6 respectively, because inner catalyst action has produced anion and cation moves to minus plate 8 and positive plate 9 respectively, has produced electric energy.The hydrone that produce this moment then flows out by water delivery pipe 7.In order to observe whether leakage phenomenon takes place in the hydrogen input process, outer shroud at hydrogen input pipe 5 is provided with annular hydrogen gas sensor 10, observe so that the data that observe are passed to controller 12 inside, guarantee the safe handling of fuel cell by data wire 11.
