Measurement and augmentation of effective thermal

The effect of variation in pressure is supplemented with other effects when the gas in the bed is hydrogen instead of non-reactive gas, because with exposure to hydrogen, the metal alloy particles react with it to make metal hydride. There is a swelling effect due to hydrogenation of these particles.
