Or the past several years, fuel cells and hydrogen have been very hot topics in the news. Unfortunately, unless you are a well-funded university or a large corporation, purchasing a fuel cell or hydrogen electrolyzer has been next to impossible. I've studied and researched fuel cells and hydrogen for several years, and I find them fascinating and technically challenging. It was always frustrating to learn only from books, without any hands on experience with real equipment. This lead me to...

With winter local heating degree days at approximately 6,500, the auxiliary heat performance level was calculated at 14,404 BTUs per year, per square foot.

In the electrolyzer process, water is distributed to the anode side of the membrane. With sufficient voltage, the bonds between the hydrogen and oxygen in the H2O are broken by electromotive force (EMF) and the catalytic action of the platinum. The membrane segregates the H2 from the O2. The proton migrates through the membrane and recombines with the returning electron. We then have one proton and one electron on the cathode* side becoming H2. *Anode and cathode are defined by the direction of...

Water Powered PV Tracker

The author's water-powered PV tracker. hotovoltaic panels produce the most energy when oriented L perpendicular to the sun. So a panel mount that follows the sun's arc can increase daily output by up to 50 percent in summer, and up to 20 percent in winter, when the sun moves through a smaller arc. Of course, the degree of benefit depends on how much unobstructed sun exposure a site has throughout the day. Seven or eight hours is enough to make tracking pay off. I am fortunate to have more than...

H mazing and fun These are words I use to describe Hall-effect sensors. You probably already own several of them. Automobiles use them to detect speed and relative location of rotating parts. Hall-effect sensors are also finding their way into consumer electronics. In fact, almost any application that requires a long-lived switch can use them. This article presents a circuit that uses a Hall-effect sensor to measure DC currents up to 200 amps. A Hall-effect sensor is a magnetic field detector....

Not recommended for domestic hot water Flat plate collectors are most commonly used for low-temperature applications up to 140 F 60 C , such as residential domestic water heating and pool heating. Water passes through parallel copper tubes bonded to a flat copper sheet under glass, all enclosed in a weathertight insulated frame. For higher temperature applications over 140 F , evacuated tube collectors are more efficient. The design of evacuated tube collectors reduces heat loss caused by...

What Does A Pem Fuel Cell Weigh

Diy Hydrogen Fuel Cell

Membrane and nickel electrode screens for the PEM electrolyzer. Careful assembly of a cell stack is critical to good operation. With concerns for gas flows, conductivity, and proper contact pressures, assembly becomes very labor intensive. Even with the best commercial designs, the labor cost component is high. Proper design and automation can address most of this at the commercial level. We did many calculations of performance based on variables such as gas flow, temperature, and pressures. It...
