Proton exchange membrane (PEM) fuel cells are the fuel cell of choice for automotive and backup or portable power applications. An EU-funded consortium has extended PEM operating conditions in order to penetrate new markets.
The PEM fuel cell is conceptually a relatively simple electrochemical energy conversion device. In practice, however, getting the fuel cell to operate reliably under the required operating conditions for extended periods of time is not so straightforward. For example, high temperature (above 100 °C) and humidity affect membrane performance, which requires the right amount of water to function.
