The utility model discloses a
hydrogen fuel
cell carbon paper deformation detection device which comprises a
universal testing machine, an experiment pressing block, an experiment
cushion block, a polar plate
carbon paper stacking structure, a video
extensometer, a concentrated
light source and a
microscope, the polar plate
carbon paper stacking structure is arranged between the experiment pressing block and the experiment
cushion block, and the universal experiment
machine is configured to provide continuously changing packaging force and uniformly transmit the packaging force to the polar plate carbon paper stacking structure through the experiment pressing block and the experiment
cushion block, namely, the mechanical environment of carbon paper in a galvanic
pile is simulated; the concentrated
light source is configured to provide brightness, and the video
extensometer and the
microscope are configured to observe the form change of the carbon paper in the polar plate carbon paper stacking structure after continuous stress. The device simulates the in-
pile mechanical environment through the
universal testing machine, and directly observes the real form change of the carbon paper in the flow channel through the optical detection technology, thereby being beneficial to improving the
cognition on the internal structure of the electric
pile and guiding the design of the electric pile.
