Abstract
A metal air cell system comprises a frame structure configured with variable airflow paths. The variable airflow paths provide alternatives between direct open loop airflow and semi-closed loop air flow, wherein air is at least partially circulated around the cell components. This is particularly useful for operation in different temperature environments. The open loop mode is useful for high temperature environments, and the semi-closed loop mode is useful for low temperature environments.
