The energy stored in xylose splits water molecules, yielding high-purity hydrogen that can be directly utilized by proton-exchange membrane fuel cells.
FORBES: Could Hydrogen Breakthrough Revive The Fuel-Cell Car?
Tropical fruit supplier Fyffes has warned of higher banana and pineapple prices due to rising fuel costs and adverse exchange rates.
There are two dominant flavors of fuel cell: proton-exchange membrane (PEM) and solid oxide.
The company said improved yield expectations and costs were offset by unfavorable changes in fuel prices and currency-exchange rates.
It also develops its own PEM (proton exchange membrane) fuel cell generators and has a growing business in China, where it will power the buses for the 2008 Beijing Olympics.
On Tuesday morning, extra fuel was delivered to the exchange, enabling it to run for 40 hours, and plans were to further top up the supply as the day progressed.
The authors believe their system could combine the advantages of methanol as a hydrogen carrier and of proton-exchange membrane (PEM) fuel cells for efficient energy production.
Gordon is luring more energy clients with such services as an online exchange where refiners can establish fuel prices in real time, rather than send out a price list once daily, and can verify the credit status of potential customers.
FORBES: Third time's a charm for this little data provider. Or is it?
An unrealistic exchange rate has led to shortages of fuel and other imports.
But until recently they have suffered from a low power-to-weight ratio, unlike the other sort of room-temperature fuel cell, the temperamental and costly proton-exchange-membrane device, which several firms hope soon to use in motor cars.
Some even employ proton exchange membranes that move charge around the way a hydrogen fuel cell does.
When times were good, there was enough money sloshing around to fuel equity markets (Hong Kong's strength) and foreign-exchange transactions (Singapore's forte).
