A vital part of enhancing the ability of students to learn is identifying the barriers associated with the student’s achievement in his/her field of study. In the Manufacturing and Mechanical Technology fields, like others, there exists an intimidating experience barrier between faculty, professionals, or technical experts and novice students. The participation of students in the design and fabrication of a Proton Exchange Membrane (PEM) bipolar plate machining fixture aids in eliminating this barrier by making Fuel Cell production possible even to inexperienced technology students. The process of manufacturing a fixture for the production of hydrogen fuel cell and hydrogen purifier plates requires careful planning. Through the use of our designed fixture it is possible to teach students how to use a CNC milling machine with relative ease while allowing for precision part machining. The setup of the fixture allows students to observe the necessary measures to properly machine a part while also teaching them the benefits of fixtures in the manufacturing industry. The design of the fixture is a multi-disciplinary utilization of resource in a learning environment. The Fuel cell plates that were to be machined on the fixture were made of a variant of Low-Carbon Steel. The choice made to machine the fixture out of High-Carbon Steel was made in order to prevent deformation of the fixture. The resistance to deformation of the fixture was essential in the quality control and assessment process. The resulting consequences of using this material for the fixture pose significant issues in the fabrication process. This introduces the students in the manufacturing technology discipline to tooling setup to form the fixture in an accurate and economical fashion. The High Carbon Steel fixture necessitated the use of Carbide cutting tools in order to maintain the desired tolerances throughout the part manufacturing. Once the manufacturing process of the fixture was complete, assessment of performance consists of the utilization of this fixture to machine multiple fuel cell plates. Students were asked to setup the fixture and utilize such in the fuel cell machining process to test their understanding of the logic and methods that establish fixture use in the industry. Student utilization of the fixture proved to be useful to students in order to gain a thorough comprehension of the associated manufacturing process. Students will be assessed based upon their achievement, efficiency and precision in setting up the fixture and the following execution of the fuel cell plate machining process. A student evaluation survey will be administered to a participating group and nonparticipating to measure the benefits of this approach described in this paper.
