Abstract
The functionality of handheld and portable electronics has advanced to a level where existing battery technology is being stretched beyond its limits to meet the runtimes demanded by consumers. As a potential solution, direct methanol fuel cell technology is approaching commercial viability, but there are still concerns regarding energy density, cost and reliability, especially at power levels of less than 50 W. Direct hydrogen fuel cells can address many of these issues, and as such offer a viable alternative fuel cell solution to the power needs of portable electronic devices.
