Proton-exchange membrane fuel cells (PEMFC), also known as polymer electrolyte membrane (PEM) fuel cells, are a type of fuel cell being developed mainly 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 ...
A fuel cell is an electrochemical energy conversion device. Fuel cells differ from batteries in that they are designed for continuous replenishment of the reactants consumed. This is a partial list of companies currently producing commercially available fuel cell systems for use in residential, commercial, or industrial settings.
Ballard Power Systems Inc. is a developer and manufacturer of proton exchange membrane (PEM) fuel cell products for markets such as heavy-duty motive (consisting of bus and tram applications), portable power, material handling as well as engineering services. Ballard has designed and shipped over 400 MW of fuel cell products to date.
The HT-PEM fuel cell was developed in 1995 for operation at higher cell temperatures aiming at lower sensitivity of PEM fuel cells regarding impurities. [3] Thus HT-PEM fuel cell technology is one of the youngest fuel cell types and HT-PEM fuel cell systems have been produced since the early 21st century by several companies.
Hydrogenics is a developer and manufacturer of hydrogen generation and fuel cell products based on water electrolysis and proton-exchange membrane (PEM) technology. [2] [3] Hydrogenics is divided into two business units: OnSite Generation and Power Systems.
standard off-the-shelf PEM fuel cell systems available from 10W to 5 kW, or customized fuel cell system configurations up to 150 kW; premium H-1000XP 1 kW stacks with peak efficiency of 59% proven during testing at Shell Eco-Marathon in Asia; ultra-light and compact Aerospace from 200W to 1,000W. fuel cell powered Hydro car
Direct methanol fuel cell. Direct methanol fuel cells or DMFCs are a subcategory of proton-exchange membrane fuel cells in which methanol is used as the fuel and a special proton-conducting polymer as the membrane (PEM). Their main advantage is low temperature operation and the ease of transport of methanol, an energy-dense yet reasonably ...
Ruthenium and platinum are often used together, if carbon monoxide (CO) is a product of the electro-chemical reaction as CO poisons the PEM and impacts the efficiency of the fuel cell. Due to the high cost of these and other similar materials, research is being undertaken to develop catalysts that use lower cost materials as the high costs are ...
