with the configuration shown in fig3 the honeycomb rotor 1 can exchange heat between the hot exhaust gas 19 and the cool inlet air 17 also moisture from the exhaust gas 19 can be adsorbed on the honeycomb rotor 1 and desorbed by the inlet air 17 the additional moisture may increase the efficiency of the fuel battery 18 because of the different oxygen concentrations it is important that mixing between the exhaust gas 19 and the inlet air 17 be minimized the present invention enables this to occur although the above embodiments describe the honeycomb rotor 1 as containing a moisture adsorbing agent it is possible to perform sensible heat exchange between gas a and gas b using a honeycomb rotor that contains no moisture adsorbing agent furthermore heat exchanger examples were given for exchanging heat between gases such as gas a and gas b however the invention can be used to exchange heat between any gases such as between nitrogen or hydrogen even if heat exchange is performed between different kinds of gases the amount of gas mixing is very small that is because the heat exchange equipment of the present invention is constructed as described above when the heat exchange equipment performs heat exchange between the gases flowing in plural passages the mutual mixing of the gases flowing in each passage can be made extremely small furthermore the heat exchange equipment of the present invention minimizes mixing of the gases while maintaining a high heat exchange efficiency moreover the passages and the charge zones of the heat exchanger of the present invention may be completely sealed so that gases are not emitted with sealing the gases flowing through the passages are not discharged to the atmosphere therefore the.
