Protonex Technology Corp. is launching a product for RVs: the M250-B, a
250-watt fuel cell (about the size of a microwave oven) that uses
methanol and offers a quiet, nearly odorless way to keep lights on at
campgrounds. Protonex has not yet priced the M250-B, but it could
initially sell for $8,000 to $9,000, with the price dropping in the
future. The company is also planning to market the M250-B directly to
Protonex Technology Corporation, 508-490-9960.
