    Abstract: An electrode catalyst layer that suppresses degradation due to repeated starting and stopping and has excellent durability, and a membrane electrode assembly using the electrode catalyst layer. The electrode catalyst layer is an electrode catalyst layer used in a polymer fuel electrolyte fuel cell, which contains carbon particles which support catalyst, a polymer electrolyte, and a fiber material which is at least one of a carbon fiber and an organic electrolyte fiber, and the thickness of the electrode catalyst layer after performing a start-stop test from 1 V to 1.5 V for 10,000 cycles is 70% or more of the thickness of the electrode catalyst layer before the start-stop test.

    Abstract: A congestion information display system includes: a storage unit configured to store a prediction model which enables prediction of a congestion status of a facility; a prediction unit configured to predict a time when the congestion status of the facility is changed from a first congestion status to a second congestion status, based on the prediction model; and a display processing unit configured to display, on a display device, prediction information indicating that the congestion status is changed at the time predicted by the prediction unit.
