... is also a possible option, it causes significant temperature gradients and thermal stress. As an alternative, a compact heat exchange reformer (CHER) with a plate-fin co-flow or counter-flow configuration is proposed. Such a system integrates the heat management and reforming in one compact unit...

... at 750 ° C , and (v) 5RedOx cycles at 600 ° C . The strength is measured by the ball-on-ring method, where it is calculated analytically from the force. In this calculation the thermal stresses are estimated from the curvature of the half-cell. For each treatment, more than 30 samples are tested. About...
