I mentioned that I had a wonderful conversation in the Pueblo Bonito Emerald Bay pool with a young man from Arizona. One of the things he was interested in was Proton Exchange Membranes (PEM). Wikipedia defines Proton exchange membrane fuel cells, also known as polymer electrolyte membrane (PEM) fuel cells (PEMFC), as “…a type of fuel cell being developed for transport applications as well as for stationary fuel cell applications and portable fuel cell applications. Their distinguishing features include lower temperature/pressure ranges (50 to 100 °C) and a special polymer electrolyte membrane.”

I came across a Seeking Alpha report on “22 Companies With Market Cap Over $50 Million and 100%-Plus Sales Growth Forecast for 2011-12.” Included in that list are several companies involved in PEM or solutions in alternative energy:
Ascent Solar Technologies, Inc. (ASTI) - $2.70
ASTI is a development stage company formed to commercialize flexible photovoltaic (PV) modules using a technology. The company’s manufacturing process deposits multiple layers of materials, including a thin film of copper-indium-gallium-diselenide (CIGS) semiconductor material, on a flexible, lightweight, plastic substrate and then laser patterns the layers to create interconnected PV cells, or PV modules, in a process known as monolithic integration. The company’s thin-film PV modules require less than 1% of the semiconductor material to achieve the same power output as a c-Si-based PV device.
Hoku Corp. (HOKU) - $1.99
HOKU formerly Hoku Scientific, Inc., is a diversified clean energy technologies company with three business units: Hoku Materials, Hoku Solar and Hoku Fuel Cells. The company has three operating segments in two industries: Fuel Cell and Solar. The Fuel Cell industry is comprised of the fuel cell segment. The Solar industry is comprised of the photovoltaic (PV) system installation and the polysilicon production segments. Hoku Corp. installed the first six out of a planned total order of 28 Siemens-process reactors at the Polysilicon Plant and in April 2010, produced polysilicon using two of the six reactors. The company is a provider in PV system installations. Under the name Hoku Fuel Cells, Hoku Corp. operates its fuel cell business, which has designed, developed and manufactured membranes and membrane electrode assemblies (MEAs), for proton exchange membrane (PEM) fuel cells.
Disclosure: I have no positions in any stocks mentioned, and no plans to initiate any positions within the next 72 hours.
Let’s follow these two and add other companies that are in this industry.
