PEMFC, Proton Exchange Membrane Fuel Cell, takes high power generating efficiency, close-to-zero pollution in emission and noise, great availability in modularized combination and high mobility as the most competitive advantages, has been gaining much focus in recent years. PEMFC is already seen as one of the new and sustainable energies and is included in implementation from policy-making of countries and also in extensive researches from well-known institutes.
PEMFC takes hydrogen and oxygen as fuel. Oxygen can be obtained from the atmosphere while hydrogen can be taken from hydrocarbons (for example, natural gas, methanol, coal, light oil, etc.), or can also be generated from water via electrolysis by solar or wind power. Hydrogen in fuel cell comes from two major sources, one is to use the side product - hydrogen from fossil industry, and later store it in cylinders with various available forms, such as in a solid, liquid or gaseous condition. However, having storage in solid form reveals the drawback of lower efficiency and higher cost, not to mention that the risk in safety and worries over inconvenience bring out the concerns in transporting, storage, deployment and replacement. In short, supplying hydrogen by storage carries even more limitations in practical use. Therefore, taking a plug-in and produce method on site for hydrogen supply in fuel cell use stands as a much more preferable choice. By utilizing hydrogen-rich gas reformed from chemical reactions of hydrocarbon, highly-purified hydrogen can be later generated after the purification process for fuel cell use.
If looking into different types of hydrocarbon, compounds from Methane and Methanol are the most commonly-seen. Reforming the reactions from methane gives complexity and forms as gaseous-type when in room temperature. Limitations and inconvenience let fall the concerns in storage, transport, and deployment again if it is being compared with liquid-formed methanol. On the contrary, using methanol as a source of hydrogen generating gives the benefits of greater purity, higher availability and lower cost overall. Thus, CHEM develops more than methanol-based reformer fuel cell but also the PEM fuel cell, which covers liquid-cool and air-cool stack availability. Our continuous commitment and efforts in R&D make us as a proud owner of the technology in liquid-cool and air-cool systems. This completes our solutions in green energy generating systems with high stability that fulfills the needs from various environment requirements in deployment.
CHEM has applied ourselves since 2008 in development of Methanol-based Reforming Fuel Cell and has also been validated with high-reliability with 400+ patents owned. Our mission of realizing the achievement in sustainability of green energy and environmental protection is once again proven with the solid performance.
