An uncommon influence for a research paper
11 May 2010 | PhysOrg.com

An article written in 2004 by Lehigh engineering professor Mayuresh Kothare and his former student (PARC researcher) Ashish Pattekar has received more citations than any publication in its field. Titled “A microreactor for hydrogen production in micro fuel cell applications,” the paper has been cited 97 times.

"The paper describes one of the earliest attempts to integrate a chemical reactor on a silicon chip for micro fuel cell applications. 'A reformed hydrogen fuel cell could provide an order-of-magnitude increase in energy storage density over today’s batteries,' the researchers say."

PARC and its partners are developing a reformed hydrogen fuel cell power system that could yield energy storage densities at least 8X those of existing rechargeable batteries such as Lithium ion, and up to 4-5X that of current state-of-the-art fuel cell approaches.

One of us, Ashish V. Pattekar, is currently at PARC, which has an active cleantech program. In a recent analysis, we have compared this approach to that of the current recharging-discharging model of supplying portable power using batteries.

It turns out that, on a per watt-hour basis, the overall cycle of generating electricity in a coal-fired power plant and then converting to low-voltage DC for recharging at the point-of-use results in almost twice as much CO2 emissions overall, compared to the production and use of methanol in a portable fuel cell as discussed in our publication—leading to significant environmental benefits as well, apart from the performance improvements over today's rechargeable battery technology.
