Fuel Cell Power: The Energy of the Future


Many scientists and engineers believe that fuel cell power stacks will be the major technology in the growth of electronic or alternative fuel autos during the next decade.

Vertical machining centers, according to Makino, a global provider of innovative machining technology, are the optimum way for machining and creating molds for the fabrication of fuel cell power stack separator plate membranes. These membranes are critical to the development of low-cost fuel cell power stacks.

Certain robust and thermally stable vertical machining centers can achieve depth accuracy of 2 microns and high surface finish quality of 0.4 microns in 40 Rockwell C steel molds, both of which are required in the manufacture of such plastic and rubber membranes.

To build the right electrochemical conversion process to convert hydrogen and oxygen from the air into water, these membranes must be of high quality and specification. The process flow then generates power and heat, particularly when used in a fuel cell stack with a reformer, which controls and regulates the hydrogen for safety.

A proton-exchange membrane separates and buffers the negatively charged anodes, which repel electrons, and the positively charged cathodes, which attract electrons. Electrons can travel across the membrane to the cathode side of the fuel cell stack, generating power. Combustible fuels burn, and ordinary batteries store and transform electrical energy as chemical energy. A fuel cell stack, on the other hand, generates direct current power.

The mass manufacturing of low-cost membranes, which might be a rising market for most machine shops equipped with technologically advanced verticals, can produce an infinite supply of fuel cell stack energy. This energy source can be used to power not only autos, but also utility companies and household generators, providing the globe with low-cost, safe, quiet, efficient, environmentally friendly, and easily available power solutions.
