Testing Proton Exchange Membrane Fuel Cells
NRC scientists are exploring ways to maximize fuel cell efficiency. In proton exchange membrane fuel cells the membrane acts as an electrolyte, or medium, transporting protons from the positive to the negative electrode. The faster the membrane can conduct the protons (its proton conductivity) the better. NRC researchers use the apparatus shown here to assess the conductivity of various potential membrane materials. The white square is a Teflon-glass composite material that holds the test membrane underneath. The yellow alligator clips are attached to electrodes connected to the membrane. |
