Polymer Electrolyte Membrane
To function, the membrane must conduct hydrogen ions (protons) but not electrons as this would in effect “short circuit” the fuel cell. The membrane must also not allow either gas to pass to the other side of the cell, a problem known as gas crossover. Finally, the membrane must be resistant to the reducing environment at the cathode as well as the harsh oxidative environment at the anode.

Horizon produces extremely compact, lightweight, PEM fuel cells at varying degrees of complexity and performance, as well as deliver hydrogen storage and on-site hydrogen generation solutions that are suitable for many specialty and mainstream applications, including consumer electronics, portable emergency power, stationary back-up power, aerospace systems, and clean transportation solutions.

Horizon supplies systems to engineers and researchers within large corporations, government organizations, research institutes and universities around the world. They are known to be the world’s lightest, most compact, and most affordable units worldwide. Horizon’s fuel cells are simple, air-breathing, air-cooled, self-humidified systems that limit peripherals to the bare minimum. The semi-integrated unit comes in a kit format for more integration flexibility.

Watch as Horizon Fuel Cell Technologies shows off a handful of devices at the 2008 Consumer Electronics Show that turn ordinary tap water into electricity, which can then be used to supply power to a range of devices – from notebook computers to mobile phones. TechWebTV’s David Berlind interviews the company’s co-founder Taras Wankewycz to find out how the Singapore-based startup has managed this bit of magic.

Chroma’s 63600 Series DC Electronic Loads are designed for testing multi-output AC/DC power supplies, DC/DC converters, chargers, batteries, adapters, and power electronic components. Excellent for research, development, production, and incoming inspection applications. The 63600′s state of the art design uses DSP technology to simulate non-linear loads using an unique CZ operation mode allowing realistic loading behavior. The 63600 series can draw its full rated current to almost zero volts. This unique feature guarantees the best loading performance for fuel cells and modern Point-of-Load devices.
