Abstract
Embodiments of suspension clamps for use in testing membrane samples used in fuel cells are provided. One example of a suspension clamp comprises a frame, a clamp member, a plurality of electrodes, and a suspension component. The clamp member is hingedly attached to one end of the frame. Each of the plurality of electrodes extends along a membrane-facing surface of at least one of the clamp member and the frame. A suspension component is attached to at least one of the clamp member and the frame and is configured to suspend the suspension clamp during testing of a membrane sample. The suspension clamp can be used to measure one or more of resistance, impedance, conductance, proton permeability and through-thickness of the membrane sample.
