Abstract
An electrochemical conversion system ( ) is disclosed having a tubular housing ( ), a thermal inertial core ( ), and a tubular hydrogen electrochemical cell ( ) which in combination define a first chamber ( ) and a second chamber ( ). A first tubular mass of hydride material ( ) is contained within the first chamber while a second tubular mass of hydride material ( ) is contained within the second chamber. The hydrogen concentration cell has a first gas diffusion electrode ( ), a second gas diffusion electrode ( ) and a proton conductive membrane ( ) therebetween. The release of hydrogen from one of the masses of hydride material and its redox reaction creates an electrical potential across the cell. The housing ( ) is adapted to transfer heat to and from the second mass of hydride material ( ). Heat is also transferred between the thermal inertial core ( ) and the first mass of hydride material ( ).
